i just got 4 IBC's this week (two 330's and two 275's)
i set up an 8'kiddie pool in my basement, and seeing it sitting there, i had to do something with it so made a filter out of a 55 gallon barrel (now i can make real growbeds for the pool!) and threw in 50 rosy red minnows and a couple dozen crayfish..after i get growbeds built, i'll be putting the yp and bg in the pool
(i already have about 45 fish - yp and bg - in my aquaponic system in the basement, using three 55 gallon glass tanks, growing green's using flourescent lights..
this aquaponics stuff is addicting!
