H2O2 treatment for ich

[maddiesmom]

If anyone has successfully treated their tank for ich with H2O2, I would appreciate precise information about how you did it. I've read so much about it that I'm more and more confused.

This is the information I would like:
Dosing amount
When to dose
How long to dose
Lights on/lights off
Equipment to turn off
What media to remove
Any nutrients that H2O2 will deplete

I have a 140 gallon saltwater tank (including sump)
Actual volume approximately 120 gallons with the following:
Cherub angelfish
Powder brown tang (the ich culprit)
Firefish
Cardinal fish
Tailspot blenny
Clownfish
Cleaner shrimp
Coral banded shrimp
Hermit crabs
Nassarius snails
Zoanthids

The powder brown is in my hospital tank undergoing hyposalinity.


Thank you to anyone able to help.

I dont think it does anything. Ich is a parasite, way bigger than bacteria that H2O2 can kill via oxidizing. They also burrow really deep into the tissue and that white dot is a thick shell that protects against h2o2. From what I read they are only vulnerable during the free flowing larva stage so really we are not actually treating the dot to begin with, but are treating against the reinfection from the new larva on the wound.

Maybe H2O2, can help prevent secondary bacterial infection in the wound that may occur due to the fishes lowered immune system.

Hydrogen peroxide doesn't treat ich. You're better off removing your fish to treat or adding a UV sterilizer (which would be effective at killing the larva stage)

H2o2 isn't for Ich, its proven itself as a broad bacterial dip/bath and treatment for velvet and brook. I have had great success using it for velvet, haven't seen it do anything to combat Ich. IME nothing is gonna solve the ich issue short of QT of your fish and a fallow period, or pull your inverts/corals and hypo your DT.

I have a UV. Thank you for replying.

I kept the tank fallow for 80 days. Removed all fish, treated with hyposalinity for 30 days and reintroduced the fish. Four days later my powder brown had ich again. He's now in my hospital tank undergoing hyposalinity again.

That sucks this hobby can be really frustrating at times, particularly with fish health. I have found Hypo to work great with tangs though. I had one show ich after a long QT that should've killed it too, fortunately I had not added him to my display yet. I then did a month of hypo at 1.09 on him and he never showed any signs after that.

I have recently ran into ich even after paying up for quarantined fish and inverts. I have been quarantining corals as well. It is what it is and now I find myself doing ich management and looking for other things to help with it. I recently watch a video with humble fish talking about treating the display with peroxide. He did advise it’s still very new and we are learning as we go. I am starting it wIth 1ml per 5 gallons every 12 hours to see if It doesn’t help. I am curious to see if anyone is trying this or has tried this approach yet.

I tried something similar and H202 was ineffective. This makes sense when you think about it. Using 1mL/5G is equivalent to 0.005% H202, which is basically water.

A bath application, similar to a freshwater dip, at 3-5% may be more effective for your fish/inverts. On that note, has anyone tried a H202 dip? We may consider doing this prior to adding fish/inverts to our system, testing different concentrations/exposure times. My gut feeling is that we will need >1% H202 for the free-swimming larval stages/eggs and >5% for the adult stage (when it has burrowed into the skin/is visible as white dots). This may be a test of relative toxicity (verus copper, for instance) if it is effective as a bath application.

EDIT: Dose was calculated using 100% H202. For non-lab applications, the maximum percentage most people can purchase is 35% (0.0017%) and drug store H202 is 3-10% (0.0005%-0.00015%)

EDIT: People who suggest that H202 treats ich may be seeing H202 reducing the incidence of secondary bacterial infections (with the low dose not affecting wound healing processes), allowing the fish time to develop IgT antibodies.
