Help with Hydroids

Alright so I have had an ongoing fight with Hydroids for over a year. I re-did my entire tank and thought I had gotten rid of them, well it appears I have not. As I noticed some on the bottom of my aquarium (I run a BB right now).

So this I stumbled a crossed this article.

"Solutions
Physical Removal -- Either picking them or burning them off the rock. Both are not good ideas. like aiptasia if you do not remove the whole entire hydroid root you risk the chance of these coming back.

Chemical Removal -Kalkwasser or super glue - you can smear kalk paste or super glue on these ... however, you chance that you won't get the whole tube emerged (remember these can get into small pores in the rock) super glueing them you risk the chance of the hydroid actually rotting in the rock. This risks the chance of causing an infection to your nearby corals.

Natural Solutions
The lynx nudibranch (Phidiana lynceus) - Only eats hydroids, especially fond of Myrionema amboinense.

Pterolidia Ianthina - sea slug that feeds soley on hydroids

Sea Urchin Salmacis bicolor- Good eater of Myrionema. but very slow & can not get into the pores of the rocks where roots are.

Diadema setosum (Sea Urchin) - Good eater of Myrionema. but very slow & can not get into the pores of the rocks where roots are. Will also eat sps corals

Flameback Angelfish (Centropyge acanthops and Centropyge loriculus) - Hit & Miss and will occasionally nip at your corals especially your sps and some polyp corals.

Dolabella auricolaria - sea hare"

I have been able to find the sea hare, but none of the other solutions (Angelfish and the Diadema setosum won't work with my SPS).

I wish I could isolate them and take the rock out, but that is no longer an option.

Any help would be greatly appreciated.

 

Cover them up with epoxy. Then you can always remove the epoxy a few weeks later.

 

That will work in the short term, but I am looking for a solution to get rid of them in the long term. I won't be ably to epoxy everything and as I found out in my last go around the always will find a way to stay alive in the crevices or somewhere I cannot get too.

 

Some kind of thermal weapon? High wattage laser?

 

So you have a picture of your tank?
