I run gfo and change it out pretty religiously seemingly even if it doesn't need it. I'm having good although slow growth. I hope to get magnesium and a few other testers soon so I'm interested in others experiences.

From what I've read phosphates are usually the limiting factor in a lot of reef aquariums. Is it worth it? Depends on you I guess
