Green algae

[Napi Napoli]

Hi

This tank has been up and running for 2 years and started with new Marco rock.
I have this green film all over my rock and if you scrape it you will find coralline under it.

P04 is .02 (P04X4)
BRS BIO PELLETS
30% MONTHLY WATER CHANGES

But I can't get this stuff to go away :headwally:

Any ideas?

Yes, easy to beat. Nanos forum, pico reef pest algae challenge thread on page 1 or 2

That rock you are holding, if treated, would be clean as new by today. Thread has a hundred pictures of cures like yours.

Ya thanks but I have high end zoo's all over my rocks and I could never take all of the rock work out of my tank.

most of the treatments were on rocks left in tank, there are about 3 or 4 methods in the thread for not removing rocks. When I treat I don't remove mine either...

cut on finger + wet hands.. no gloves? I know I'm paranoid, but I couldn't do that.
