I want to build a 20 gallon sump/refugium for my 55 gallon aquarium. I have some questions...
1. Vinyl tubing or PVC for return line and line from overflow box? What does everyone use/prefer?
2. How do you know how large to make the compartments? I'm going to have 3 : (from left to right) water from tank > refugium > return pump... My tank is a 20 gallon long (30 x 12 x 12). My baffles will be 8" high.
3. How do you run filter media (like carbon) in your sump? or do you use some other method... I've seen some sump designs with a box of some sort in the first section. Anyone do this?
Thanks.
