Dealing with some algae in my SPS

[Ultraman]

I’ve treated the tank for Bryopsis in the past with removal of the Bryopsis, but some leftover hair? algae afterwards. I’m retreating for Bryopsis, but it might be an algae that isn’t killed by diflucan.

Any thoughts on removing this challenging algae? NO3 is 8-10 and PO4 is .08.

If it was just gha, I’d suggest ordering a few hundred amphipods. For bryopsis, lettuce nudibranch and raising magnesium. This has worked for me several times over the years in different tanks.
That’s a tough spot to have algae on. I feel your pain.

I don't see direct application of peroxide being more damaging to that coral than the algae itself. Obviously I'd avoid getting any on the live coral as much as possible.

So just spray some Peroxide with a syringe to the algae?

 

[blecki]

Don't spray, that will get it everywhere. Apply it directly to the algae at the base. The algae will turn white and die in a day or so.

Peroxide will also burn the coral; something tough like a zoa you can just dip directly into peroxide and it'll be fine, but I'd be careful with an acro so you don't kill the flesh around the algae and make the whole thing STN

a few sea slugs will clear that all up in one night

I’ve got some 10cc syringes. I can fill them with H2O2 and turn my flow off, then hit the algae that way if that’ll work? Appreciate the help.
