20L sump compartment sizing

I figure I should start on my sump.
I want to use an Eheim Compact+ pump with a footprint of 5x4 roughly, I was thinking about making the return part 7 inches. (7x12)
I have a hang on protein skimmer but if I ever wanted to get an in sump one I was going to make the PS spot 8x12 inches, that only leaves about 11 inches for the middle refugium section with 1 inch between baffles.
Should I shorten the pump section to 5x12 maybe? I want the middle to be as large as possible and have room in the first part for a skimmer down the road.

Well, don't know if you have room under the tank or not, but you don't necessarily have to go with an insump skimmer. You can get one that sits outside, that will give you plenty of insump room for your macro algae to grow.

I know the basic rule of thumb is that the refugium should be at least 10% of the volume of the DT. If you fill that up at least seven inches, you will be at 4 gallons (11" x 12" x 7" = 924/221 = 4 gallons), so that should suffice. RM is right though, go with an external skimmer and make the fuge as big as possible.

Nothing good happens fast in an Aquarium
