Help.. corals covered in green algea

[ssunthar]

Hi Experts, 2 of my coral which i thought died starting to show signs of life... but it badly covered in green algae..

What can i do to safely remove them without harming the corals? Thanks.

If it was me I would tweezer and 2 minute peroxide bath or spray. The polyps would likely be unscathed but the blasto(?) I'm not sure. Either way it would need to be repeated on a regular weekly/monthly basis because that crap it just going to grow back.

Thanks, thanks. Any suggestions on the dosage of peroxide that I should use? One is a acan and the other one I believe is a blasto. I also have a scoly and a small brain on which I starting to see some green on the skeleton.. should the dosage be the same for all?

Do not use peroxide on lps. Both of those appear to be lps coming back from the dead. They cannot tolerate it well.

Tweezers and a toothbrush will go a long way and hopefully a cuc can finish it up.

Sorry. I just posted here by accident and they can't be erased.

Just to clarify neither of those pictures are of zoas or palys. The top appears to be an acan that needs some light. The bottom i think acan or favia. For the scoly and brain you mentioned...again dont use a peroxide dip on any of those.

I'll assume you have experience with those specific corals but generalizing 'lps' is incorrect. I have used peroxide on euphyllia many times for exactly this type of algae infestation in exactly the way I suggested (full 3% spray with 2 minute contact, rinse and return to the tank). They get iritated but are fully open by the next day. The algae turns white and distintegrates and gives the coral a chance.

Thanks for the warning..
