Hello all, I will soon be setting up a sump (if i can get everything figured out)....just a little 10 gallon for my 29 to get some equiptment out of the way. At the moment I have a Rena Smartfilter size 30 (waterfall, no canister yet *sighs* )...shes quite large for what she is. Now if the reef gods are with me I will hopefully be able to move it to the sump to get its bulk out of sight...does anyone know if a waterfall filter would work in a sump? or how it would work...or be best set up for that matter, if it is possible? The sump is yet to be built, I have a design in mind but it is very much so subject to change, all ideas are appreciated. Thanks!!!
