I am thinking of starting a 10g fuge under my 75g since this is all I can fit in there now. I wish I had known about it before I set everything up. But anyway, I only have two hang on the back filters and the fuge will be below the tank. How can I set this up and what are some ideas about the feed and return?
I'm thinking I could get an overflow box to feed it and add a plastic divider to keep the sand off the return pump, but to keep the flow slow enough, what size return pump would I need to push it back up into the tank? And how do you fiqure the water turnover rate that goes through it? And also how do you plumb all this? Can you hook PVC up to the return pump and overflow?
