Clean algae from zoa frag

[lastlight]

I've had two blue polyps clinging to a small piece of rubble for many months now. What started as a colony of 8-10 polyps was over-run with a thinly branching algae that weaves in between the polyps and chokes them over time.

I had the rubble sitting on the sand bed for a few weeks and it was too close to another small colony of 40-50 zoas. That colony now has a few thin green tendrils winding through it!

I have plucked nearly all of it off and it slowly comes back. Is there anything I can dip the rubble in that will kill this algae and not harm the remaining polyps? Thanks!

Thanks for the lead. I wouldn't likely try this on anything but zoas. Luckilly only 2 zoa colonies require my attention!

That guy tried 4:1 saltwater to 3% h. peroxide which is what I'm going to do.

i havent tried it yet but i hear good things, i had the same problem in my zoa tank def gets frustrating and pulling it doenst quite work. leave your zoas in the peroxide dip untill the algae fizzess then it should be gone for good i dont know

I just dipped 2 of my rocks one with zoa,s and the other with GSP in a solution of 4 parts saltwater to 1 part peroxide for 5 min each zoas opened as soon as they were put back in and the GSP opened back up the next day all the HA gone.I was really amazed at how well it worked.

I used a 1 part peroxide to 3 parts water for when I dipped to revive mine, worked like a charm! I probably only had to dip for 1 1/2 minutes or so

Yeah, I should say, I did 4 parts tank water :1 part 3% hydrogen peroxide for 5 minutes.

I've been peroxide dipping zoas/palys for a few years now. I use 10% peroxide to water and dip 15 minutes. Kills all algae, zoa eating nudies as well as their eggs(my main reason for dipping), flatworms, and other nasties. It also stops zoa fungus(my other reason). Killing algae was just a bonus.

I haven't seen these two surviving blue zoas this wide open in months. Great little trick!
