I am using an AC110 and an AC70 on 55g right now. I am heavily stocked and the water is crystal clear.
for the 400 get the online ad for petsmart for 39.00 and take it in the store and buy it. it saves you about 40.00ttt0649;1402801; said:Thanks for the responses guys. My water has always been crystal clear. Just wanted a lil more bio filtration and mechanical. I think im going with another emperor 400.
