Red algae

Wow. They look very invasive.
Hope you get rid of them.

Thanh, is the algae very coarse or soft like cotton? There are a couple algaes that seems to like low nutrient systems (i.e. zeo systems).

If it is cotton like then you can try Mexican turbos as some have had success using those. If it is the coarse stuff though it may be more problematic. I've heard of some people having luck with the combo of manual removal + a sea urchin.

Regardless of what type of algae it is though, make sure you have a decent clean up crew to begin with and they should be able to help keep a lot of that stuff in check before it gets really out of hand.

looks like red cotton or red turf algae. i've had it before and it sucks because its not the easiest to rip off the rock unlike cyano which can easily be blown off. i got a couple turbo snails that got rid of it. i have heard that some rabbitfish pick at it as well but i've never tried that. in the end, the turbo snails did the trick for me, but i did have to take one rock out and hand scrub it with a knife, toothbrush and tweezers before the turbos could do their work. hope that helps.

Bad algae, kill the rock, and then scrub it. The pores last for ever.

My 90 was killed by it when it bloomed. Everything died overnight
