So I have this stuff that has pretty much taken over my tank and I can't get rid of it. I'm looking for an ID and an eradication plan that is anything short of a total teardown.

Fenbendazole dip for blue clove polyp/hydroids.

FYI So I had more than few blue clove and what i believe are hydroids pop up on a few frags and start spreading in the frag system. I didn't want to start out treating the whole system so I picked the most populated frags to treat. I mixed 1/4 gram of Fenbendazole with 1 cup of saltwater as a...

Here it is! Fenbendazole use against hydroids

Hi all! Well after getting a lot of questions about the use of fenbendazol I figured I would write this up. This is for informational purposes and I will not be held liable for improper use. Fenbendazol must be used exactly as I instruct or run the risk of a tank crash. Now lets get to it! So...

Peroxide dipping guidelines (for corals)

A while back Justin Credabel published this chart detailing the concentration of hydrogen peroxide appropriate for dipping various genera of corals. I've used these guidelines myself a few times to remove algae from coral frags and it's been quite effective. Justin Credabel's hydrogen...

I've dealt with a different species in my tank - cutting out fine particle foods has helped tons and most are restricted to the undersides of rocks now. Not sure if this a catch all for every type of hydroid but something to consider.
