OK, maybe not a bath, but a shave? I have a clam that has two things growing on its shell. A small patch of GSP that started because I was a bit remiss in keeping it trimmed back. The second is some hair algae tha sadly is growing at incredible rate on th poor guy.

The GSP doesn't seem to bother it at all. Been ther for quite some time, touching the mantle with no noticeable effect. But, I am worried about th hair algae, cuz a) it's in my tank! (more on that later) but also, b) i worry that th algae can block light need by the zooxanthellae. So, I have been pulling it off. Of course, you can't pull it all off...

Were I to gve th clam(shell) a scrubbing, would I do more harm than good? I am thinking stainless steel wire brush? The mantle MOSTLY retracts when it is nervous, so I would need to be careful around that... I definitely don't want to harm it.

Any thoughs?
