Back of tank right side of back close up left side of back close up
I got some better photos of the back of the tank that I’ll share. I realized that I can just remove the bio balls on both sides and put in a protein skimmer on each side where the bio balls currently are without having to cut any acrylic out. Each side of the tank has two compartments filled with bio balls. One compartment on each side for a protein skimmer and the other will be a possible refugium? What are you thoughts?
I think it's best to work with the existing compartments and add/remove media. I think you only need one skimmer, there isn't necessarily a reason to have two unless that's the only way to get the capacity that you need due to size constraints.
