3% Hydrogen Peroxide (H2O2) dosing for parasites in a mixed reef tank (132G/500L)

[marinehead]

Following this thread.
currently undergoing a similar process. Have a 90 gallon stocked with 11 fishes, with a newly added Achilles Tang.
Have UV up and dosing H2O2 based on bolken’s post on this thread:

https://humble.fish/community/index...ng-for-parasites-in-reef-tank.725/post-276160

did Hybrid TTM w/ H2O2 for Achilles for 14 days prior to addition and now seeing prevalent white spots with white blotches.
It’s been 2 days now and he’s still alive albeit sluggish.
All other fish are doing well aggressively eating 2 days later.

Are you seeing any blue color on the test strips? Shrimp die pretty fast from peroxide, but the zooanthids are pretty resistant. Any snails? How are they doing?
Jay

The test strips will only arrive mid OCT. Snails are fine, my Halloween hermit is out and about his business. Abalone is still there too.

I should clarify - the “dose” you listed above is for 3% peroxide measured as 100% The dose of actual peroxide in the water will be 3% of that value.
Jay

According to humble.fish…1mL 3% H2O2/5gal (19L) = 1.59ppm. I’m using that as a gauge.

Yes, that’s the thread I was referencing too. I like the “bomb” and “rain” analogy. I have 3 spare dose slots from my REDSEA DOSER, I may drop a few more “bomb” in between the 6 hourly term, after I receive my test strips. I’m with Jay on putting some numbers on the utilization of the dosage.

Till date I had put 6/6 Acanthrus through the hybrid TTM successfully, but I won’t introduce them into a known ICH environment, till they have thicken/fatten up substantially, IMHO. As long as he’s not to stress to be eating aggressively, he will pull though, mine has.

Do let me know your H2O2 outcome!

The math isn’t working out for me. Do you mean 1.59 ppm hydrogen peroxide or 1.59 ppm of 3% hydrogen peroxide solution? If the former, the dose is too high. If the latter it works out to be 0.0477 ppm of actual peroxide, and that is close to the 0.5 ppm dose that I found generally safe for invertebrates.

I'm sad to report after careful stock taking, I found the carcass of my Blotchy Anthia...

man, that hurts. I also lost borbonius to ich. That fish was like a puppy to me. The only fish I have ever given a name to. I been keeping fish for 40yrs.

I did the following math…

1ml of 3% H202 there is 0.03ml H2O2,

Added to (5gal) 19L=19,000ml of water.

0.03/19,000x100=0.00015789% of H2O2 concentration in the 19L…

which amounts to 1.58 parts per million.

Does that make sense?

Man, did I miss him too!!!

OK, so the issue is, how long does that amount of peroxide remain active in your system and will that value change over time as previous additions react with existing organics.
(I saw a typo in my previous post: 0.05 should be 0.5)

Only the test strips will tell in 2 weeks time. Cheers!

I wonder if intermittent dosing. Maybe dose 4 days on, then 1 day off.

Why so? Shouldn’t we not give ICK a breather?

Not for ich, but for your corals that are being stressed. 1 day break wont bring on a full ich outbreak, but it might save some of your corals. Also, I assuming most of the free swimming ich has perished or severely compromised.

Some food for thoughts.

OCT 6 (DAY7) - Another Anthia (HUTOMO) bites the dust…

Are some or all of the fish still covered with ich?

Sorry to hear - as just was posted, do the fish have a large number of ich trophonts on them? If so, then the peroxide isn't working. If not, then the fish are dying from some other reason - perhaps too much peroxide?

I see on the larger fishes and Anthias. Wrasses and Sand Gobies are alright.

The water was slightly hazy better half of yesterday, I didn’t think of much except maybe it’s the peroxide…was I in for rude awakening today!

OCT 7 (DAY 8) - I was met with more hazy water and the stench was overpowering. There were a bunch of dead fishes under the corner, and some white flesh at the power heads. On close observation, both the carpet anemones were melting away underneath the sand, spilling their guts from where they hid the first couple of days.

Instinctively I changed as much water as l could muster which was about 30%, skimmer was overflowing all these while, and dumped in activated carbon which I had in backup for emergency. The water remained slightly hazy when I left for the day, but fishes are out and about.

There’s the Montipora that was bleached on Day 3 or 4 of dosing.

Bulk of the fishes lost were Anthias and the Whitetail Bristletooth Tang

I’m not sure now if it’s the dead anemones or the ick caused their death. But I’m certain the H2O2 dosing caused the death of the Haddoni Carpet Anemone pair.

For now, I’m just glad that I saved whatever fishes remain.

 

[Sleepingtiger]

dang.... this is terrible.

If you were near me and I lend you two 100g water tanks that you can use to quarantine your fish.

 

[Jay Hemdal]

So sorry to hear! Personally, I'd "call" this experiment and work a different angle. I've seen people try to "manage" ich and lose their fish and I've seen people have to sacrifice their invertebrates to an ich treatment, but in this case you are losing fish and inverts, which is a no-win situation.
