sump setup

[Baldy]

Hi all,

I have a 75g setup rigt now with a fluval 404 canister filter, and am looking at building a sump for it. I don't have much room in the cabinet, so 12-15 g is all I can fit. At the moment I have a maxijet 1200 running a remora c skimmer, and another one running a phosban reactor with bioplastic pellets in it. Is itok to return all the sump flow through the skimmer/reactor with 1 pump? I'm planning on using a mag drive 9 as a return pump which will work great split between the two. The reactor could use the extra flow anyway. Or should I use 2 return pumps?
