Ive built a 5.5g sump/refugium for my 25g reef tank and i need advice for plumbing and flow rate. One option is to have a 200 gph
overflow and a mag drive 750 (225 gph
with my 9' of head). Other option is 2 200 gph
overflows and a mag drive 950 (500 with the head). In both options i have the return line t'd off with a valved line coming back to the sump to lower gph
coming into display if necessary. Would 350/400 gph
be toomuch flow through the refugium? Would the first option be better and add a powerhead to the display to increase it's flow without having to increase the flow through the sump/fuge? This is my first sump/ fuge so advice and suggestions appreciated.
