GSP overgrowth

Like a number of coals or shall we say weeds, GSP can quickly spread.

Getting rid of it is almost impossible. GSP is very hard to get rid of. I have seen patches of GSP in FOWLR tanks doing just fine.

I sometimes just turn the rock over so that the GSP is face down into the sand. The GSP however will be back within a month or two.

You can also move a rock into your sump if dark and leave it there for a few months and the GSP will slowly disappear.

Got the same problem. It's a constant battle peeling it off with a dental pick and also have a fair bit of rock in the sump. Stuff in the sump been there probably close to 6 months and though haven't seen the polyps in months, fleshy part is holding on. Sure it will come back if I show it light.

I've thought about taking a rotary tool and gouging it off on my rock. Not sure if that's safe though.

I use boiling water to tame any that gets out of control on me. I have it growing up most of the back glass on my reef, and sometimes it creeps across the sand and gets on my rocks when I'm not looking so I have to get it with the boiling water. It takes several treatments though over the course of a couple months. I use a length of rigid airline tubing on the end of a big 200cc syringe. Always gotta be onnit. Best thing I have figured out so far.

How attached to your rock are you? I advised someone locally to just trade in their GSP covered rock at our LFS for some new liverock. They made the trade and the store was able to sell it within a week. Theres always some new person to the hobby who likes the stuff.

I've personally just used a butane torch to get rid of small patches. I've tried leaving the rock in the dark for several months but I find GSP will just go dormant and then will grow again right away when illuminated once more.

bit mean knowingly letting it loose on the unexpecting newbie. Sort of the 'friends don't give friends GSP' thing.
