This is my 600 gallon pond, I have a 30 gallon mechanic and biofilter, I set up a timed flood and drain system on a 7' pvc post with 3" netted baskets with herbs and strawberries. I installed a 8' x 12' sunscreen to protect it from falling leaves. As I get more experience on this I will switch to blue tilapias, so I am trying to find a place near Orlando where I can get some tilapias for my pond. I am barely getting into aquaponics so I am open to any suggestions you may have....
