which makes COMPLETE sense. Unfortunately, its tiny more like pea stone. And the customer base for the tank, is four feet high, plus a wierd shaped, taller type of tank. I did the whole measurement yesterday and divided it by 220 whatever.....came up with 125 tank size. Its just an odd ball tank. so to reach the bottom, I need a chair and half my toro in the tank
I need some kind of substrate. I have undergravel filtration.
