and I cant boil the rock and kill all the mushrooms thats way I really dont know what todo ,
My LSF told me they are beneficial for the tank and people buy these algae from them and they have some in their Show tank !

But I just want them out of my tank

welcome to the reefing world lol (jking)so heres the thing we all have tough decisions and yours prob is to lose your mushrooms or get them scraped and put them somewhere else and then kill off the grape. another idea is to scrape what you can and epoxy the area so no further growth can happen if theres no nutrients then theres only one other source for food and if you block out the light then wha la

Remove the rock and place it in a dark sump or circulating bin of water until the algae dies. In my experience mushrooms can survive longer in the dark than caulerpa. But if you're worried you can always cut some of the mushrooms off of the rock to leave in the tank. That is how I rid most of my tank from that nuisance algae. The last little bit of it I plucked out with tweezers. FYI I don't keep any of that crap anymore. Not even in a refugium. Chaetomorphia and gracillaria are much less invasive.

I had a similar problem with a small rock that had zoas on it.
I know it really made a big difference when I started running GFO.

You'll find it doesnt grow back nearly as fast once you do manually remove it.
however, i think you might be stuck with it as long as you want to keep the 'shrooms.
