I have keep for almost 9months and my red algae is always coming back to haunt me! sad sad!!!!!! My coral are grwing well for mushroom and zoe but others are not doing too well. Probably I dont dare to feed too much as I worried the algae will be back. I have almost 15 fishes in my tanks and most are small size fishes and i only feed a cube size each day once. I dont think it is alot but why still red algae still growing? I have bio pellets, carbon filter, phosphate removal. I have a protein skimmer too. I have chaetos too! but it seems to be not working at all. Please advise?
