hydriods

Ok, dinos seem to be non-existent (once again, YAY!) so ready to attack the hydroids. Anyone with experience doing the epoxy? I have small patches of these on almost every rock in the tank. It will be an extensive job.
I'm full of questions:

• Should I do one rock at a time or start replacing the live rock in my tank?
• Doing one rock at a time will be a lengthy process and I will have to dismantle my whole rock work. Have any of you done this successfully? Any issues arise?
• Should I do it over a couple of days for less trama to the live stock?
• What brand of epoxy did you use?
• How long to leave it outside the tank before returning it to the water?

Here we go for a ride on the crazy train, LOL.

Bump.

Thank you in advance!

I never did try the epoxy trick so I'm not sure. If I was to do that though I'd only do a few patches at a time. The underwater epoxy is not always the nicest to work with (it's more of a putty than an actual adhesive). I could see this getting kind of expensive since even the cheap epoxy is still like $10 per tube.

Sorry I wish I had better experience to draw on. All I really know is that shortly after adding a potter's angel, the hydroids started to disappear. I had also read that pygmy angels (any of the Centropyge sp. angels) will nip at hydroids so I still think that might be worth a shot for you.

Those are hydroids for sure...
upside down jelly fish??

Hydroids will also retract when you touch their "crown"

I have tried every trick in the book to rid my tank of these as they do sting some corals and can grow prolifically.

NOTHING works though.
The epoxy trick might work if you have 1 localized patch of them but in my experience, they just grow through or around the epoxy in little time.
now I just suck it up.
