Tank design question

[lotsoftats]

Is a 20l sump/fuge big enough to be efficient for a 75g? or should I do a 20l sump and gravity feed a 10g fuge?

Know before you answer that question here is what I want to do:

I have a 75g that I want to divide into 2 sections each 24x18x20 and have 2 different pairs of clownfish and there Anemones....It will be clownfish and nems only on each side...In your opinion what would be my best option?

Use something dark to divide it or you will have clowns with concussions. Tough to fit a sump and refugium in a 20L. I'd use the 10 for the refugium so you have more room in your sump. Every inch is priceless.

Yeah that was what I was thinking 20 and 10....the divider will be 1/4" black acrylic.

I agree to gravity feed the refuge.
