Nausithoe are a polyp form of jellyfish that look kinda like hydroids (see links below). While not as invasive as some hydroids they have been in my tank for well over a decade. Initially they were sparse and did not seem to harm anything. Now they have gotten out of control and are causing coral irritation as well as being an eyesore. I've thought about kalk paste but the sheer number of them is overwhelming. Has anyone used an Aptasia Zapper on Nausithoe? If no one has actually tried zapping them do you think it would work?
Zapping Nausithoe?
