Ok, so I have 1 green severum, 1 carpinte, 1 GT and 1 JD with 2 silver dollars for dithers in my 135. I'm running 2 emperor 400 biowheels and do a 40% water change weekly. They are all under 4 inches at the moment and I was wondering what everyones opinion on this setup is. Will it work in the long run? I'm mainly concerned with bioload.
