Aqua Farm Update 7 Jan 2014 Dead Pump

,
The Aqua Farm hasnt been doing very well.  The air pump seems to have died.  For a while it was not making very good bubbles, and the water was not reaching the upper tray.  The water wouldnt circulate, and the system was not functioning properly.  I tried cutting the airline tube at different lengths to make better bubbles, and it seemed to work, but eventually the pump stopped making any bubbles at all.  Im going to ask Back to the Roots if theyll send me a new air pump.  I may also try using an aquarium air pump next to the fish tank to supply the bubbles for the air lift.  Either way, Im not happy with the system right now.  Im hoping that I can tinker with it and make it work better.  On the bright side, I regrew some green onions in one of the grow pots, and ate them in a tasty turkey soup (Thanksgiving leftovers!).

Edit 10 Jan 2014 - Back to the Roots is going to send me a replacement air pump.  They recommended placing it outside the system, sitting vertically next to the tank.  Theyre also sending me new seed packets, and suggested that for the basil and lettuce I may need more light.  Great customer service!





I apologize profusely for the vertical video.  :(

105 Gallon Apartment system PVC or no PVC

,

So, Ive previously written about my windowfarm that Im building.  Im also currently working on a 105 gallon system for my friend +Evgeny Pogorelovs apartment.  Its going to be a basic flood and drain on a timer.  We have a 55 gallon aquarium, which will feed into our 50 gallon stock tank grow bed.  Were currently planning to have about 5-6 tilapia, and grow all kinds of veggies.  Ill update with pictures soon.

Right now, were constructing the frame that will hold the system.  Weve cut all the wood, and painted it all white, and now we need to assemble and put it on wheels for easy mobility.  The next step is plumbing; well use a 200 GPH pump.  Were hoping to stay away from using PVC due to conflicting reports about PVC leaching chemicals into water over time.  However, this may only apply to soft PVC, not hard PVC.  We need to do a little more research before we buy pipes.


Heres what Pogo wrote to me about PVC in farming systems:


Found some resources that cite PVC as leeching dioxin, pthalates, and other toxins into water / food. Definitely want to avoid PVC piping in any operation we start. The safer alternative is biodegradable EVA plastic. 

"See: www.aaa.dk/pvc PVC plastic is an environmental and public health hazard because dioxin and other persistent organic pollutants can be emitted into the air, water and land during its manufacture and incineration.

In addition, PVC products can leach toxic additives during use, and thus may harm patients receiving certain medical treatments.

PVC has come under scrutiny by the European Commission since 1997 resulting in the release of the Green Paper in July 2001 that highlights the dangers associated with its disposal, and in April 2001 the European Parliament adopted a resolution calling on the Commission "to introduce rapidly a policy on the replacement of softPVC, in so far as the current risk analysis of phthalates indicates that it is desirable to reduce the exposure of people and the environment".

These concerns have led increasing numbers of health care providers to search for alternatives. Grenaa Central Hospital, Denmark, substituted 95 percent of its PVC-products with safer alternatives without compromising safety and care, and found many of the alternatives to be more cost effective."

Disaster System switched OFF for 7 hours!

,
On Sunday, my parents came over to stay... My mom, as usual, goes around the house looking for something to clean, arrange, or replace... Monday night, she noticed a power socket switched to ON in the living room... Without caring where the inserted plugs lead to, she flipped the switch...! :facepalm:

6am in the morning, after 7 hours have passed, I went outside to check my system and realized that it was silent... The pump wasnt pumping water!

25 to 30 guppies died that day... The tilapias were fine as they were saved by the aerators backup power but the water had a slight rotting odor probably due to accumulated ammonia...

Floating guppy carcasses sucked by the drainage pipe...
 The thick layer of gunk collected at the bottom of the guppy tank may have also contributed to their death as it contains loads of greedy bacteria competing against them for the remaining precious oxygen...

Some gunk netted out...

As for the plants, strong winds have been the main problem this few days... After being knocked over by the wind repeatedly, all my okras had given up and none could stand upright properly now... I got to think of a solution fast...



Monstrous Kang Kong...
 Thanks for reading... :-D

Brief Video Update

,


We have green life!  The system is cycled and growing small plants.  Zeus, our tilapia, is doing fine.  Were probably going to eat him soon, and put in some ornamental fish.  Id like to have a bit more plant growth before making the switch.

Low pH in the apartment system but growth is good

,
I checked out the system this week, and it seems to be doing well.  The brown algae in the water is slowly disappearing.  The veggies are growing well, though the strawberry seeds that I scattered in one pot don’t seem to be growing too quickly.  My friend hadn’t checked the chemicals recently, so I did while I was there.  The pH was very low (<6), but everything else looked ok.  The ammonia was 0.5ppm.  Nitrite was zero, and Nitrate was 160+ ppm.


I added 6 capfuls of API’s pH up.  I decided that I didn’t want to rely on my friend checking the pH and adjusting, so I added enough pH up to bump up the pH to around 7.  Normally I wouldn’t want to raise it more than 0.2 per day, but I didn’t want to risk losing the bacteria and have to re-cycle the system.  My friend added a little water the next day, and checked the pH.  It was about 7 – 7.2, which is ideal.  Hopefully this weekend I can visit for a few hours to clean the canister filter, and plan out new fish that we want to put in the fish tank.  We’d also like to mount some small lights that we have onto chains above the grow bed.  Another issue is that the water draining is somewhat loud, so I want to figure out a way to muffle the draining water.  Here’s some pictures and a video from my visit to the system.

System Update 28th Mar 2012

,
A heavy down pour two days ago had increased the water level tremendously. On Tuesday morning, I found that the bottom part of the outlet pipe had fallen off into the fish tank. Surprisingly, the siphon still works! I will leave it as it is for now since its providing more aeration than before. The shortened siphon outlet also slows down the outgoing flow since a shorter downward pipe means less water within the outlet pipe to contribute to the siphoning action by gravity.
Nice water effect!

Today I went to the pasar tani (farmers market) near my house to buy some vegetables to grow in my system. Although my setup is new, most of the fish tank water as well as the expanded clay was reused from from the old system. There is still plenty of nitrates in the water as I didnt plant much in my old system. So in order to remove those excess nitrates, I will plant Kang Kong (Water Convolvulus), a Pegaga-like plant (is it Pegaga? can anyone confirm?), and the famous aquaponics monster - The Mint... Kang Kong and the Pegaga-like plant will probably do well since they are aquatic plants.
Before I plant them into the grow bed, Ill have to wash their roots first. I can see the Mint anticipating its new found territory.

Pegaga-like plant was planted in bunches of 4 - 5 plants with their roots still intact. For the Mint, I removed their roots and bottom leaves before inserting them into the media. Letting them grow new roots would be better than risking their old conditioned for soil roots to rot. I also had sprinkled some Tomato, Chilli and Kailan seeds 3 days ago. Ill be expecting them to germinate in a few days time. Ive also inserted 6 Barbados Cherry seeds in to the growbed - "sigh..." - but I also read that they take 6 to 12 months minimum to germinate and only 5% will be successful.

I threw half of the kangkong into the guppy tank. Some mint and pegaga were also thrown in together. The kangkong will root in the water and provide hiding places for guppy fries.

The other half of the kangkong was thrown in to the larger fish tank for my Pleco to munch. Ah! The water has a green tinge! I am happy for that as I have never had an algae bloom in any of my systems before.

Guppy feeding frenzy; Food consumed in 3 seconds!
Thanks for reading! Will post another update soon...

Some System Updates!

,
Heres a quick update on the greenhouse aquaponics system in Delaware.  Unfortunately I havent been down there frequently enough to take care of it as much as Id like, but Ive got a radial flow filter built, and I just need a larger pump and tubing to hook up the sump tank and second grow bed.  Ill be working on that in the next few months.


My buddy Graham in Trenton, NJ has been working on his indoor IBC tank setup.  Here are some photos that I took.





Also in Trenton, my friend Jon built this really cool bookshelf with an integrated fish tank.  I talked to him about making the bookshelf above the fish tank into a small grow bed with lights mounted under the shelf above.  That would make a slick bookshelf / aquaponics system.  Check it out!

Pros and Cons of Different System Types

,
Commercial Aquaponics


Ive been trying to compare the pros and cons of different types of aquaponic systems recently.  Right now, Im working on constructing a 105 gallon setup at my friends apartment.  Were making a simple flood and drain system, with a 50 gallon grow bed.  Filling that grow bed will require almost 200 Liters of expanded clay or some other media.  All that media is going to double the cost of our system.  We were thinking about alternative methods, such as expanded shale or even something like legos (but we dont have nearly 50 Gallons of legos).  The cost of buying a grow media for a large grow bed is so high, that it really got me thinking about alternative systems.  Heres a list of pros and cons of various aquaponic systems.  If you know anything that I havent listed, please leave a comment and Ill add it to my list and credit you.


Media Bed Systems
Chift Pist, Simple Flood and Drain (Ebb and Flow), Constant Flood (Continuous Flow)
Pros
· Self Cleaning - The grow media filters out the fish waste
· A media bed performs three (3) filtering functions:
    · mechanical (solids removal)
    · mineralization (solids breakdown and return to the water) 
    · bio-filtration
· Media provides better plant support and is more closely related to traditional soil gardening because there is a media to plant into

Cons
· Expensive growing media

A Typical Media Bed


Chift Pist
Pros
· Pump is in sump tank away from fish and wastes
· Water level in fish tank remains constant
· Great if you have a tall fish tank
· Larger water volume because of sump
Cons
· Extra equipment required (sump tank)
· Must have tall fish tank or stand
· Can take up larger footprint

Chift Pist system


Simple Flood and Drain / Ebb and Flow
Pros
· The grow bed can be separated from the fish reservoir
· Simple design - Only two major system components - lower cost
· It is easy to understand and learn
· Great if you have a tall fish tank
Cons
· Requires a timer or bell syphon
· Pump is in fish tank, exposed to fish and waste
· Water level in tank fluctuates a little


Simple Flood and Drain system


Constant Flood / Continuous Flow
Pros
· Same as the Simple Flood and Drain, except when you remove the timer, the system is constantly flooding
Cons
· Pump is in fish tank
· Plant roots can become waterlogged, and areas of the grow bed can become stagnant and anaerobic as the flow of fresh water through the bed moves around any blockages


Constant Flood system


Deep Water Culture (DWC)
Pros
· Resistant against water temperature and pH fluctuations
· Excellent root development due to easy access to oxygen
· There is plenty of surface area for the beneficial bacteria to grow
· Very good for lettuces and leafy vegetables – used extensively by commercial farmers
Cons
· Requires additional filtration to remove solids
· Large plants such as tomatoes, cucumbers, etc. can be difficult, if not impossible, to support


Deep Water Culture system


Nutrient Film Technique (NFT)
Pros
· Both components (fish and plants) may be decoupled from each other whenever required and can/do operate independently of each other if required.  I believe this is important in a commercial situation because it allows fish or plant production to continue when and if there are any problems with the other component
Cons
· Water susceptible to temperature fluctuations
· Requires additional filtration to remove solids
· Roots that die and detach from plants can cause blockages in water flow
· NFT is only really suitable for certain types of plants, generally leafy green vegetables, larger plants will have root systems that are too big and invasive, or they become too heavy for the lightweight growing gutters

CCRES AQUAPONICS

 G.F.A Advanced System Ltd.









Aquaculture is the farming of aquatic organisms: fish, molluscs, crustaceans, aquatic plants, crocodiles, alligators, turtles, and amphibians. Farming implies some form of intervention in the rearing process to enhance production, such as regular stocking, feeding, protection from predators, etc. Farming also implies individual or corporate ownership of the stock being cultivated.



For statistical purposes, aquatic organisms which are harvested by an individual or corporate body which has owned them throughout their rearing period contribute to aquaculture, while aquatic organisms which are exploitable by the public as a common property resource, with or without appropriate licences, are the harvest of capture fisheries.

 

Grow Fish Anywhere


G.F.A Advanced System Ltd. has developed and implemented a unique patented fully closed, zero discharge intensive aquaculture system that is suitable both for fresh and sea water fish. The system is based on an extensive research done by Prof. Jaap Van Rijnof the Hebrew University of Jerusalem. The system prevents environmental pollution, and can operate in any climate regardless of the availability of water resource or proximity to the sea. The system has been tested and proven on a scientific basis and is now operated commercially.


Our Unique Aquaculture Technology

Unique Aquaculture Technology



GFA unique system overcomes several limiting factors that restrain the output and effectiveness of fish farmers.


The accumulation of inorganic nitrogen and organic waste products in intensive fish culture systems is one of the major limiting factors preventing further intensification. Inorganic nitrogen (especially ammonia and nitrite) is toxic to fish and accumulates in the pond water through excretion of ammonia by the fish and by breakdown of organic solids. Most of the treatment systems used in todays aquaculture facilities are designed to facilitate the growth of nitrifying bacteria which convert ammonia to nitrate. A drawback of the ammonia removal by means of nitrification is the subsequent increase in nitrate in the culture system. High nitrate concentrations ought to be prevented since, at high concentrations, nitrate has a toxic effect of fish and might be converted to nitrite with an even higher toxicity. Daily flushing the ponds at rates of up to 25% of the total system volume is generally practiced to avoid nitrate build up.
However, such a practice often causes considerable environmental impact and is prohibited in many countries due to environmental and public health considerations. With respect to organic waste products, most aquaculture facilities are designed to mechanically remove the organic waste from the culture tank. Often, the concentrated organic waste is discharged from these facilities without post-treatment and this practice together with the discharge of nitrate-rich effluents is considered a major limitation in the development of intensive fish culture systems.
Due to the need for daily water exchange, existing intensive fish culture systems are situated in areas with an ample clean water supply. Thus, for economical reasons concerned with water supply and discharge, culture systems for marine fish (including recirculating systems) are exclusively situated in the vicinity of the sea. Marine fish farming, whether practiced in seacages or in land-based farms, is often subject to intensive public debate as the farms discharge nutrient-rich effluents in coastal waters of often heavily populated areas. Sustainable farming of marine fish is therefore a major challenge in todays aquaculture development.


Our system developed by Prof. van Rijn and G.F.A Advanced Systems is a zero-discharge system suitable for the culture of freshwater as well as marine edible and ornamental fish. No water exchange takes place and water addition is limited to compensate for evaporation losses only. The system reduces inorganic nitrogen and organic wastes from pond water by means of the induction of several microbial processes among which: (1) fermentation: the conversion of complex organic waste compound to low molecular weight organic compounds, (2) nitrification: the conversion of ammonia to nitrate and (3) denitrification: the conversion of nitrate to nitrogen gas and the conversion of low molecular weight organic compounds to carbon dioxide.


For more information on Denitrification


Key Advantages:
• High output- Avg. density of 70 - 100 kg of fish per m³ of water
• Maximum freshness- Within a day from farm to plate
• Zero discharge- No environmental pollution and Bio-Secure
• Produces premium fish- No antibiotics, mercury and lead free fish
• Both saltwater and fresh water
• Grow Fish Anywhere (G.F.A) - Can operate in any climate regardless of the availability of a water resource or proximity to the sea
• Non native - enable the growth of non native fish in any region

Sustainability


At GFA, our sustainability vision is focused on water conservation and energy savings technologies for the local market. We believe that the future of our food consumption will belong to environmentally friendly and sustainable production driven by economic sense for high quality healthy product.
The main aspect of the GFA systems is its Water Conservation and Pollution preventing. Our production system allows the production of marine fish species in 100% recycled water systems. 1 kg of grain needs 1,000 liters of water to grow to maturity. Our unique system enables us to produce 1 Kg protain (within the fish) in less than 10 liters loss due to evaporation and do not discharge any waste water or pollution in the process.
Another key aspect is Feed Practices. GFA systems that grow the fish in land based tanks, enable the improvement of feed usage. Our system allows, in comparison to sea cages (nets) and open pools, to better managment of the Food Conversion Ratio (FCR). Less food for each Kg of production means lower production costs and a real help for protecting our environment.

105 Gallon System Update coming soon

,
Ive been slowly working on my friends 105 gallon system.  We have the canister filter installed and pumping water.  We have our media in the grow bed.  We have the bell siphon installed and working.

Unfortunately, we lost the color code chart for testing pH and other chemical levels, so were waiting on a replacement chart to balance our water chemistry before starting fishless cycling.  Hopefully in the next week, or less, well receive our replacement color chart, and well be cycling.

On a side note, I received an Arduino as a gift from a Reddit gift exchange.  Im learning to use it, and will ideally be able to set it up to monitor the system.  I know it can monitor water temperature.  Im hoping I can also set up sensors to trigger supplemental lighting when it is a gloomy day.  Im also wondering whether I can use pH sensors and other chemical sensors to monitor everything about my system.  Id love to also build an automatic fish feeder, but thats down the line a bit.

Anyway, keep a look out in the next week or two for an update with pictures and video.

Aquaponics System 5 Steps To Success

,
So, you want to set up an Aquaponics system? Dont worry though sounds complicated it is really an easy job. If you have some basic knowledge about the system you are ready to go. I believe you have the on the basics of the system).
basic knowledge about the system like what it is? And, how it can help you (If you have any doubt check my earlier article



However, there are some important point which you might still interest you. Let me mention five such things which will help you attain some amazing results.



Proper Location: the place has a crucial impact on the success or the failure of you aquaponics system. It is highly important for the plants and fish to grow. Factors such as optimum temperature (not too hot not too cold), presence of natural lights (for the preparation of food for the plants), absence of external harsh weather are very important. Make sure no chemical of other harmful substances are present in the water. It can kill both y our plants and fish.



Oxygenate the water: Oxygenating is essential for the fish. Lack of oxygen can make your whole system fall apart. Oxygenate daily to make you fish happy. Happier the fish better the output of the system.


Choosing your fish accordingly: The aquaponics system normally works with any kind of fish. Yet, there are some restriction on the type of fish you can grow depending on the law of the state. It is for your best interest that you check the laws of your state before choosing the fish. Here is an article you can read about the best fish options for your aquaponic system.

Height of the system: Make sure the system doesnt go about your waist level. That is the best height so you dont need to bend over while harvesting. It will make the daily care routine easier to implement.

Additives: Generally in an aquaponics system the fish provide the nutrition for the plants and generally you dont need to add anything from outside. But, there are cases when the fish will not be able to provide enough nutrients for the plant. In such cases you might need to supply  nutrients in the form of iron, calcium or potassium carbonate.

The aquaponic system itself is a very easy way to achieve a bounty full of veggies and fish in a short period of time. Follow the five steps mentioned above and you will have a great success in your attempt to grow organic foods for your family.

If you are really serious about Aquaponics system and want to give it your best shot check out this source of information.

105 Gallon Apartment System Assembling the Frame

,

 Tonight I had time to stop over +Evgeny Pogorelovs house after work and we assembled the frame that will hold our 105 gallon aquaponics farm for his bedroom.  The total cost so far is about $250, and we still need pumps, piping, media, and fish.  Estimated cost is about $350 for the entire system.  It is also larger than we need, so we could fit a second 55 gallon fish tank, and a second 50 gallon stock tank on the frame.  Pogo moves out of his apartment in September, so well decide where it will go, and if well upscale at that point.




We started with the shelves that we made last weekend, painted and ready to be assembled.

Heres our 50 gallon stock tank and 55 gallon aquarium.

Attaching wheels

Not too difficult at all

DRILL!

Assembled!


Moving it into its future home

The frame was build larger than necessary to allow us to make the system larger in the future.


Thanks +Evgeny Pogorelov.

Aquaponics System Know the basics of Aquaponics Design

,
aquaponics fish tankIn this edition of Gardening ABC we will discuss one new concept in gardening. We have already discussed the basics of vertical gardening and container gardening and their benefits In our earlier articles. Today we will discuss Aquaponics system.

Most of us have heard about hydroponics, it is a system where plants are grown without using soil and cultured in water only. Here they generally use chemical fertilizers for the nutrition of the plants. Aquaponics system goes one step further. It uses fishes in the water to provide the nutrition to the plants. Thus it makes the total system organic. Like hydroponics, it also does not uses soil. Roots of plants are generally kept directly in the water. In some cases roots are supported by some rocks inside the water.

The Aquaponics System:
Aquaponics system 
The three main parts of this system are:
Fish tank
Grow bed
Pump to move the water from the fish tank to grow bed.

The water from the Aquaponics fish tank goes to the grow bed. There it provides the much needed nutrition to the plant. The plants in the system act as the cleanser. It clears the water and then drains the water back into the fish tank. The secret of success in this system is maintaining proper balance.

In this culture choices of fish and plant is very important. It is better to use fresh water fishes which we generally found in landlocked lakes or rivers. On the contrary if you choose sea water fish you will limit the option of plants severely.

Try to avoid ornamental fishes such as Goldfish if you have any plans for eating fishes.They are commonly treated with chemicals and some times can cause cancer in human. The best options which we can use are common fishes like cat fish, Tilapia, trout, etc. You have to adjust the size and temperature of the water inside, once you decide on the type of fish. For example fish like catfish grow long so you need enough space for them.

Also concentrate on your gardening goals, like if your plan is to grow cool weather plans like spinachor peas avoid fishes which loves warm water.

If you are really serious about starting an Aquaponic system for your own I will suggest you check out this amazing source of information.



Benefits of following Aquaponics system:

Aquaponics system works most of the time independently. The fish and plants work together and the water gets recycled. You just need to replace the water which has be evaporated from the system. Once you created the system you don’t need to add fertilizers regularly or weed it.

It gives you the chance to reduce carbon footprint as you don’t need to travel to get your food.

It reduces the water consumption in gardening.
