YOud have to have alot of fish..... LOL. I used to have over three hundred gallons worth of Aquariums.... Varying from One BIG tank in the living room to Vivariums, Turtle tanks, Kids room tanks. Then there was the small pond I built in the front driveway.... (dont ask lol) out of Cinder block and a pond liner... So when I discovered the topic of Tilapia ...... and Aquaponics..... I thought.... Wow no brainer.... My head spun around... I could do this.
Even though my house is in the desert it gets too cold for Tilapia in the winter without heating the water 75-85 optimum temps.... Could work around that too. Maintaining the proper ph levels in a big tank is easier.... but you have to be certain you arent adding something that will change that.
Though Tilapia are very very tough and will live in a WIDE variety of ph and salt levels, Fluctuation within that system would not be good.
People here are using those three hundred gallon totes and slicing off the top eight inches for a filtration bed. that drains back into the tank then the fish waste is drawn off and circulated through grow beds whereupon it returns to that final filtration spot. THAT in its self is an ecology.
Actually each Aquarium Tub pond bucket..... you raise fish in has an ecology with many many different contributors, from micro organisms to insects to even molds and fungi. The food that goes in..... also feeds the other critters that live with the fish....
Sorry I am not making sense... I was up very late last night.
something like this video
BTW I am now adding a Grinder to my list of required tools...... LOL. Wether it be for IBC tote Separation or cutting my 11 gauge aviary cages..... Love the tool. You can use a jig saw or use a circular saw with teeth for wood to cut plastic but they heat the plastic up sometimes so you have to make sure to check the cut as you go or it can heal up....
The only thing I would change is the standpipe and the way the water circulates. I want an Ebb and Flow system. Easy enough to do with the existing drain in the center.... They are pretty easy to build but it takes a bit of trial and error to make it work right. The ebb and flow allows the water to attain a specific height without drainage.... Then once that height is achieved the siphon action causes the whole upper tank to drain out to a specified level. The idea is to keep the plants hydrated yet not create an anaerobic atmosphere to damage the roots.
I think Using the IBC tote for a first time learning experience. And to get your fish's water going well. This is the perfect height for me for gardening..... I cant kneel at all.
edited to add..... Dang they had a Bell Sipon video right on the page..... Wow.
deb "off to go find her Ebb and Flow video"
