fish water

Youre right Leafmite, goldfish would be best...they are the fish that have the highest food/poo ration and like to dig in the bottom so they leave the most organics in their water

My local hydroponics store has a koi/carp pond that they use to water there plants..... but they also have some cym. and phal. in semi-hydro. There in hydroton, water is circulated in to the pots via 1/4" soaker hose wrapped in circles. They seem to do very well.
