This is true, and so is what was said about future tanks. You could put a piece of sponge over the intake and it would restrict the flow further I would think.ChannelCat;2345750; said:i have the AC110 on my 20 gal tank and its flowing on 100% I dont thing the current would be too bad for breeding. Especially since you can turn it down. Id get the 110 and turn it all the way down
