I've got a 3 chambered sump. The first chamber is where the water drains into from the aquarium. It has an eggcrate shelf. The second chamber goes up over a baffle. I've got my skimmer and plan to put some grape algae there like a refugium. The third chamber flows over a baffle again and has my return pump.
I need to add some filtration. What goes on the eggcrate shelf in the water return chamber? I was going to put a foam filter block there but wasn't sure what is best.
