Fingerling setup. 60 gallon blue barrel with U siphon pulling waste from the bottom emptying into 5 gallon water bottle with drain attached to bottom. This has a U siphon over to a 15 gallon drum which is now filled with orchard netting and matala and a pump back to the blue barrel. There is also an aquarium air pump and stone going to FT. I threw this together, because the Tilapia fry got too big for the 29 gal aquarium i had them in.
