So I got red slime algae again for the 3rd time about in 18 months, in all the times I have used red slime remover with no ill effects at all to corals or fish, the red slime went away but it comes back in a few months, I have a 75G tank with 9 fish medium and small, my corals are Zoa, Mushrooms, Polyps, Kenya Tree, big Sun Coral, some Xenias over all softies, and 6 RBTA small and medium in size that keep splitting on me, (that’s another problem) but over all I have to say that my coals are all flourishing, I have a big MegaFlow#4 sump with rubble rock and DSB refugim with macro algae, my skimmer is the Eshopps PSH100H, I run carbon & GFO and bio pellets, I don’t have hair algae problems at all. I feed my fish only frozen food, I feed them everything. I would consider my tank to be well feed. So why is the red slime coming back, I don’t want to keep using it even that their where no ill affect, I want to take care of the cause of the problem, I’m starting to think that my skimmer is just under rated for my tanks need. (Not that I have the $$ for a new bigger one) What do you think?
