Does anyone know what kind of algae this is and how to get rid of it? Thanks

I can't see the pics for some reason Bud. Maybe it's my cellphone.

I will wait till someone else chimes in.

I think you're right from the pictures I looked up. Would you know how to get rid of them?

can you remove the rocks they are on?

DjGhostRider · Jun 17, 2015

I'd have to tear apart the tank. They're all over the right side and a few have spread to the left.

I have successfully peroxide burnt those off other tanks by doing the rock remove/external treatment but i think they are too tough to burn off by adding peroxide to the tank water. we'd have to google or comb the forums for a fish that w eat them, while not eating corals im really challenged on natural anti hydroid methods that dont involve really hard to find sea slugs i think i once read. a tank drain is possible but thats too much initial work, to see if any chemical cheat is even possible you'll have to pull a test rock, zap w peroxide, let sit a min soaking, then put back in and watch for a death phase and timing and actually any regrowth in that spot before doing the big tank work. test it is my offer

Thanks, might just give that a run.

I read that Aptasia-X works; have any experience with that?

brandon429 · Jun 18, 2015

Sure I wouldn't discount that, or straight kalk slurry, or even fire burning as an option as I've burned lots of things off the rocks but most of these are removal treatment options

The eradications for hydroids range and aren't as pinpointed as typical invaders we w just have to try test areas to see
