I've had it on and off over the last few years on this tank or that. I usually use the chemiclean and it disappears within a day or two. You can use it to get rid of your problem but you really will have to address the issue so it does not come back after it's gone.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
