Pond Boss Forums INTRO Questions & Observations Can talapia be raised above ground swimming pools?

If you use the ground up peat you could try to make a fluidized bed with it. Basically you need a pump strong enough to keep the peat (smaller the better) suspended in the water column (in the 55gal barrel) and make the return high enough for gravity to keep the peat from flowing out of the barrel.

I have never tried it but it could be a cheap experiment for you.
