How to remove algae off coral

[Lelegance]

I have some algae that has accumulated somehow on my favia. Dont know how this happens since it is in the right flow, but it did. How can i remove it? A toothbrush would damage the tissue i would think. The algae looks like a brown film, dont think it is detritus but i dont know. Thanks for any help!

Probably need a better Pic under whites. I can't see what you are talking about

Can you turn off your blues completely? Algae normally won't grow on living coral tissue. Need a clearer pic to see what's going on.

Heres a photo where the flesh has receded:

Possibly necrosis if algae is directly on tissue like that. I've had tons of algae grow on coral plugs and usually grow all around the coral. But never has it directly grown on tissue. You can use 3% peroxide solution with part tank water. Each coral has a different tolerance though.

The presence of algae indicates the absence of tissue. Dab a q tip in hydrogen peroxide and be real careful.

I have had this issue before with a perfectly healthy lepto, algae grew straight onto the tissue and killed it.

I'm sorry I have no idea whats wrong with it but its doing poorly.

Can you give more info on your tank? Tank age, water parameters, type of lighting and flow, any other corals in the tank and how are they doing?

There is also some algae on these clove polyps, if not algae, what is it?

More likely the algae irritated the coral into recession then took hold and continued.

Thanks! Any ideas on prevention? Just clean around the coral with a toothbrush?

If your confident in your tests look like your flirting with disaster. I can't see anything in those pics but you need to get your nutrients up for multiple reasons.

Yes prey it's not dinoflagellate. Post some better pic when you have time.

If you can remove the coral, dip in peroxide.

That coral looks hangry. If you can find it some shade and try to promote as little growth as possible till you get some nutrients in there. As long as your not relying on it for anything else cut your skimmer off and throw some food in there.
