I have a refugium set up with two small clumps of chaeto. It has never done well since day one even with plenty of nutrients it likes and an opposite light schedule of my display tank. Parts of it turn clear and it doesn't really grow. I want to use the macro alage to control my NO3 and PO4 to an extent, however hair algae wins the battle. Currently my PO4 and NO3 measure .25 and 5 but I believe the hair algae is hiding a lot of the PO4 levels in my tank. I have a protein skimmer and I was thinking of getting a phosban reactor. Is it worth having a my refugium/sump or should I just turn it into a sump? If I am skimming a lot of the nutrients out and binding the rest with chemicals does it make sense to keep my refugium?
