Removing GSP from Live Rock

[Delphinus]

Take a screwdriver or a coin or a credit card (or similar thin plastic thing) and wedge it under... Eventually you should find the magic spot where afterwards it will just peel off.

Thanks. Its just really taken off in the last few months. I've had it in my tank for 2 years and it really hadn't moved so didn't give it much thought. Lately, I see growth daily.

I'll give that a try and see if I can get it off. Otherwise I may just have to rescape my tank to keep the rocks isolated I guess.
