Hydrogen peroxide dipping

Bobthebrewer · Jul 28, 2022

I thought I read where you could dip your corals in hydrogen peroxide to kill the green hair algae that’s growing on the frag plugs. I tried it because I’m fed up with hair algae. I guess I either did it wrong or maybe using hydrogen peroxide is a myth I don’t know. Pretty sure the two corals that I dipped are dead. Any feed back would be appreciated. See photos.

what kind of coral did you peroxide dip? Zoa's will survive cause they survive anything, I've put zoa's into 100% pure peroxide and they still survive and thrive.

But not all corals will survive, I would guess probably most wont

Most people dip to long. As soon as it bubbles take it out. Zoas only. Sudden death for euphyllia.

I dipped a Zoa and a Candy Cane. Both for 15 minutes. Obviously this was a bad choice.

Very bad. I think the 2 minute recommendation is to long and un necessary. The algae will die after a shirt dip. The frag might still have some algae on after the dip but it will due. Don't toss the zoas yet. They might come out some day. Good luck!

I never dip in full strength 3% H2O2. Just spot treatment. I'll dilute it for dipping. Basically just enough to see bubbles and only for a few minutes.

H2O2 is one of my favorite dips for struggling or algae ridden corals. Lugol's is great too, but not for algae.

Sometimes my zoas will take a week or so to open back up. Candycane have been fine. What dilution did you use with the H2O2?

+1 love Spot treating algae with h202, I like toothbrushing areas 1st, then treating area with cotton swab or direct pour of 3% h202, leave out for ~5-10mins, I then may or may not rinse and put back into the tank. This works great for lps skeletons that have algae on them as opposed to dipping the whole piece.

usually dipped zoas in h202 is ok, but they will sometimes look terrible afterward.
I like spot treating them as stated above as opposed to complete immersion. Many times I just pour h202 on top of a zoa frag and let it sit out for 5 mins.

always works better if I can scrape the algae in some fashion ahead of time and dry the area too prior to peroxide application.

I didn’t dilute it.

Good to know. Live and learn. Thanks.

I heard keeping it bubble for 15/30 seconds is the way. Idk I’m looking into it further myself though

After the 15 minute dip, as it turned out both corals are making a comeback. Albeit a very slow comeback. However so is the algae. This is a practice I wouldn’t recommend.

So I just dipped a lobo frag that had some rust brown flatworms in a 4:1 RODI water and H2O2 solution for about 3 minutes... I assumed since people do RODI dips that it would be instead of saltwater. Ton of flatworms removed, but the lobo not looking too hot rn. Guess what I'd like to know is. Is it dead.

I dip all my new coals in a 1 + 9 dilution of store bought 3% Hydrogen Peroxide. 5 mins max.

Never harmed any of them. Just kills hitchhikers and algae.

You dilute the h202 with tank water
