red cotton algea

[Chin_Lee]

also manual extraction is needed if your tank is over run. Usually with a good sized water change and sihphon tube to suck them red cotton balls out. good luck - they seem to just disappear after some time but the snails and manual removal helps to get rid of it that much faster
if you don't feed your tangs for some time, they will start to eat it too..... but might not be the most animal friendly method.

I had luck getting rid of it in my fuge using Mexican Turbos and a sea hare.
