Can anybody help, I've unfortunately let this coral get out of hand and it's taken over my tank has anybody got advice on the easy way of getting rid of it!
Looks like cloves to me from the pic and I have the same problem AND should have NEVER bought them! I usually pull them off the rock, give away, throw away.....good luck!
No way you can chisel all of those off. They're covering everything. You could smother them in aquamend maybe. That's a tough situation! Not sure if anything eats them.
I've used Joes Juice to get rid of pest palys before. I turned off all movement in the water and covered them in it. Of course you couldn't do your whole tank at one time. Do it in sections.
I would remove the rocks. I have heard that when they are stressed and about to die they give off toxic chemicals and poison the rest of the tank. Those and star polyps were the first thing I was warned about when I started. The star polyps were supposed to be just annoying however the xenia is more damaging I had heard... just Murr 2 cents
doesn't look like xenia to me. Looks like what are commonly called "wood polyps" which are either an anthellia or clove polyp. I had some start to take over a tank a while ago and I just pulled the rocks out and let them sit in the sun for a few weeks. Then scrubbed them real good before cycling them in a separate system for a few more weeks. After that I added them back to the main tank. I killed the rest off a little at a time in the tank with vinegar.
Acid bath for GSP. These die easier though I believe. The sun should take care of them, but honestly you might as well just acid wash them if you are letting them dry out. They become dead rock. Might as well make it very clean dead rock and start it over.
