Return Pump Question
 

I picked up a Mag 9.5 to use as a return pump for the 65 gallon tank. My question is this: Is it best to run the foam intake attachment on it or do most of you run them with the intake open?

I am thinking the foam will just be a nitrate factory unless I wash it every few days and it may also block any critters from the refugium part of the sump from making their way into the tank.

I run my Mag 18 without the foam for the reasons you mentioned. Unless you feel like cleaning it regularly I think its best not to use it.

Okay, thanks guys. No foam it is!
