I have these tough tufts of what I'm assuming are green hair algae (or at least a green algae) that is resistant to my crew of urchin, blenny, hermit crabs, limpets and margarita snails. They are VERY difficult to scrub off with a toothbrush. They showed up a while go but since then my chaeto and mangroves have really taken off and nutrients have fallen.... although phosphates are a little high at 0.25 (I have GFO in my sump right now). Is there another CUC member that I should consider adding? I've been hesitant to add tangs and other larger fish as I've wanted this to be mostly an invert tank. Or be patient and let them take care of themselves since it isn't getting worse?
Also.... this tank is only 5 months old but already went through the 'uglies'. Really the only nuisance algae are these tufts. Which isn't a huge aesthetic issue really.
