Ideas for getting GSP off rock??

[mike31154]

Don't think there's really a quick/easy solution that won't potentially harm other stuff. Manual removal as you've been doing is probably the best way. It's what I do. Tweezers, picks, narrow/sharp implements make the job a bit less tedious. Get a little lip started by prying with a sharp/flat implement & then the tweezers or forceps.

It's a bit like weeding a garden, very therapeutic for some folks, not so much for others. Character builder for salt water hobbyist & often a factor causing some to throw in the towel! Hair algae anyone?

Thanks for the responses so far everyone. Keep em coming. As for the Youtube links, with the growth of this stuff Im thinking that I'll need the biggest one they make...

I've intentionally let my GSP grow for two simple reasons it kills the purple star polyps and it looks cool

However if I need to remove it I just use a broad flat screw driver and scrape where I don't want it and it works well but it does take some muscle power and occasional swear word

Yea best bet is to scrape it off

May have to try the epoxy suggestion. I've tried scraping but due to the nature of this rock is is about impossible to get off I'm finding. The other rocks, no big issues but ths pile, wow, they are cemented on there good. I'm going to keep at it though. May have to just pull the rock out and work on it while its on a table... Try that way..
