I need to get rid of mushrooms, How?
 

I have too many mushrooms, unable to remove rock or pry off. I hate to do this, but is there a way to kill them? Without affecting others.

Kalk paste and a syringe needle. (Used to be easy to get synringes at UFA, but they moved and I don't know where to, so, that one might be an interesting challenge now..).

May take repeated attempts but usually works pretty good. Better to get the pastey kalk goo at the bottom of the kalk slurry since it's "more potenter" and if you turn your pumps off it's generally pretty targettted (ie. without affecting others).

What if I don't have Kalk paste. Would Tailored Aquatics Aptasia killer work?

Does anyone have any syringes for sale?

Thanks Tony.

you can get a syringe over the counter from any drug store...

Thanks, I will check with Shoppers, since it is close by.

Why would you want to KILL a coral? If you have to many then give them away, I am sure somebody would take them.

Because mushrooms will kill his 'more desirable corals' and because they can not be easily removed from the rock. If any amount of their base is left behind it will grow a new mushroom.

Kalk pasting should work but if you want to try something different you could cut out as much as you can and then scrub the rest of the rock while siphoning out the debris at the same time. A tooth brush zip tied to a hose should work.

Vinegar will also work. I used to do 1 syringe of kalk and 1 of vinegar every other day to kind of balance each other out. Try to limit to about 5cc each time so as not to throw your tank off. They were both equally effective but you have to get it into the body cavity and tissue.

I have found a turkey baster and boiling RODI water will work most of the time. Not an exact method but cheaper than any other. I started with one mushroom, now I take about a dozen per week to the local LFS and have about 125 in my tank that I have not successfully removed yet.

One thing to note is not to kill so many at a time as it will hurt water quality.

It really does suck am working on a new tank and was originally planning to use my current rock. Now most of it is useless and I see mushrooms as equivalent to aptasia.

Bingo.
Once you start aggravating them by trying to cut them out or to paste them to death, they'll reproduce like crazy.
I had the same issue and luckily for me I knew someone that would take the 'shrooms for free along with the 2 gorgeous huge lovely pieces of LR that they were growing on.
Other option is too remove the LR, take it outside, scrape the area as best as you can and let it dry out. Then recure.
A third option is take the LR with 'shrooms to you lfs and get credit.

Good luck
