Ok so another one of these darn things came back. How much of vinegar or lemon juice do I put on it and how often?
Thanks again

I use Aptasia X from Red Sea. It has worked well for me. From what im hearing its just Kalkwasser. I nuke the little buggers a couple dozen at a time with no ill effects on the tank.
