So my tank is finally almost back to where I want it. The next hurdle is for me to attack the dreaded palythoa. My tank is slowly being over run by the zombie buttons and it is a loosing battle. Most are on rocks that I can not remove. I started vinegar injections tonight, and will kalk paste ones that are on level ground, but does anyone have an aipstasia zapper or laser I could borrow maybe? Anyone have any other suggestions on getting them out without taking the rock out?
