Hydrogen peroxide

[Mjrenz]

I've seen people mention on here that they use hydrogen peroxide as a coral dip. I have a zoa rock that has some gha and what looks to me like bryopsis, there's very little algae in the rest of the tank. I was considering the peroxide dip but wasn't sure of the right way to do it and if it's actually safe. Can someone with some experience please enlighten me?

Zos are tolerant usually, but dipping isn't ideal


It contacts uninvaded areas for no reason

Better to be surgical, external outside the water: scan with tweezers and remove all anchored growths

When clean by dental detail cleaning, then go back over clean areas, not invaded ones, with directed dab of peroxide vs broad coverage

Rinse off after a bit

Then put back in

I knew I shouldn't trust YouTube, thank you!

You can dip in peroxide but it's harsh on the zoa IMO.

Better to follow @brandon429's suggestion.

However, if you're treating for a bacterial or similar issue with zoas a mild peroxide bath is a good stand in until you can get furan-2.

I do dip my frags from time to time in a diluted hydroperoxide bath. No harm whatsoever, they are open again the next day and all that algea like green hair algae dies off leaving the zoa/paly with nothing that irritates or disturbs it.

I did this as well, as a last resort of sorts on two zoas I thought were close to dead. Algae died off the plugs, zoa's recovered. Can't say I was surgical, but scraped off what algae I could, then used a test kit syringe to squirt diluted peroxide onto the base of the zoas and frag plug without getting a lot on the face of the corals. It really worked well, but I may have just been lucky.
