I have recently been dipping zoas in Melafix to see if it has any effect on the hydroids. I know it won't harm the zoas, so I have been doing 1/2 capful of Melafix in 1/4 gal of tank water for 10 min. It kills the larger hydroids. After about 24 hours the polyps are gone leaving just the stalks. I don't know if the stalks can regrow a new polyp though. At least its progress. I've had these buggers for 7 years now and I am going all out on them. If I cannot rid my tank of them, i will be tearing it down completely which I REALLY do no want to do.

I also have an email in to Carol Keen who created the product Hydroxs. I hope to be able to use this product as a dip, then move the coral to a new hydroid free tank.

Another option I am exploring is hydrogen peroxide. I know people are now dosing this in their display tanks to get rid of bubble algae and dinos, and it is very harmful to hydroids. It would be great if just doing a dosing regimine of hydrogen peroxide could wipe out my hydroids.
