Ok, I have an Emp 280 on a 40 gallon which is fully cycled, and I have a 110 Aqua Clear which I'm cylcing with Danios and sludge on my 15 Gallon hospital. I would like to move the AC 110 when fully cycled to the 40, but does it have more beneficila bio capacity then the EMP? I'm quite the believer in the Bio-wheel, but the thing has given me sleepless nights......In the AC 110 I have the sponge and biomax, and am going to probably add another bag of biomax....
