I'm interested too... I've got a 55gal fishtank which i am on using. I started a grow in it using a bucket with polystyrene floating in it and the light over it. (filling the tank didn't make sense cause i'd use ALOT more nutes, i reckon alot would go to waste when i change water). The plants seemed to like it.

Hope my 2cents helps. Ha ha ha
