Experience with hydrogen peroxide on corals.

For my battle with bubble and gha in my 20 gal reef this is what I did, not really a dip but whole tank thing. it kinda gives a whole tank super strength dose for a short term. Forgive me if this gets confusing. I emptied out 5 gallons of water, then dosed 3% strength h2o2 at 2ml per gallon for full tank volume (40ml total) Applying via syringe over the bulk of the issue areas in my tank. I Let it sit for 10 to 15 minutes while prepped to put clean mixed Salt water back in. Then put the new water in somewhat diluting the strong mix in the tank. This worked great for me. I had 3 Random Acros, frog spawn, acans, Zoas, and 2 chalices for corals. Inverts: tuxedo urchin, peppermint shrimp, blue leg hermits, and a few misc snails. 1 clown fish and a war paint goby. The only real scare for me was the urchin dropped all his/her trinkets immediately after putting in the H2o2. Algae turned white and started to dissipated over the next 24 to 48 hrs. Fish inverts and corals all survived. I then did another 5 gallon water change after 72 hrs to try to get the remaining dead algae out. All tanks are different and this may or may not be your thing. I am battling a Dino breakout and this did not seem to “cure” Dino’s but did a great job on the algae. I don’t recommend this if you questioning H2o2 but might help build a little confidence. It does wipe out algae if directly applying.

I’ve used it on zoas, chalices, favias, and acans. I do 1 part 3% hydrogen peroxide 4 parts tank water. Let soak for three minutes. Rinse, then put back in tank. Works well and doesn’t bother those types of corals too much. I’ve heard of people doing a stronger mixture and I have tried it but I noticed it stresses the corals a lot more.

Gonna give this a shot today. Very helpful thank you! I have a frag of zoas with some gha between the polyps it's driving me nuts!

It's great for cleaning algae out of hard to reach crevasses, but I don't think it's a good solution. Just keep doing your maintenance and mature your reef. Eventually the algae will go away once everything is stable and you've got a more regimented feeding schedule.

Trying this for the first time. Yesterday I followed the Justin credible guide, gently removing with a toothbrush as much as i could during the dip and all seemed good. I didn't notice much if any fizzing/bubbling during or after the dip and the hammers seemed to love it tbh. I'd go as far as to say the looked brighter and more vibrant instantly which I wasn't expecting at all but sweet ok. Today, over confidence may have got me. Dipped one last hammer coral and also some kind of bubble coral in a stronger solution. Fizzed like crazy, bubble coral puffed right up, then deflated and still looks ticked off. Basically the same reaction from the hammer albeit less dramatic. Looks like sh** now too lol. Fingers crossed for the little guys

Ime, torches were hit or miss for me. Out of 4, 1 didn't do well and just never recovered. Acans took a hit but recovered in about 2-3 days. All other corals took the dip like a champ. I was using 50/50 ratio for 1-2 minutes. I dosed it 1ml/10gals in my tank for hair algae and everything did good but my pod population took a little hit.
