Hydrogen Peroxide and Aquarium Pathogens

[eatbreakfast]

Would dosing H2O2 be helpful as an intank treatment for some of the commonly encounters aquarium pathogens?

This is just purely speculation and curiosity. But H2O2 has been increasingly used as a reef safe treatment for nuisance algaes and dino problems. The reason it works, according to my rudimentary understanding, is that it is an indescriminant oxidizer. That oxidation property is similar to what we see in ozonizers and uv sterilizers. It destroys simpler lifeforms.

There has been research in how it is an effective disinfectant against bacteria and protozoans, though not in all stages. However, just as ozonizers and uv sterilizers don't entirely eliminate pests and pathogens, but keep them at bay so as to give the fish a better chance of not getting an overwhelming infection, would H2O2 help similarly?

Just speculation, but was wondering what the disease experts though.

I haven't used it personally. Noga lists H2O2 as potential treatment for marine velvet @ 75ppm for 30 minutes (in a HT/QT), with a retreatment after 6 days. It's also listed as a treatment for parasitic isopods (1250 ppm for 30 min.)

I think it can help, but doesn't remain active in the water long enough to achieve complete eradication (i.e. zap all the free swimmers.) And how does one know when it is safe to redose?

IMO; as an antiseptic, it has great potential to help treat bacterial infections (as a bath) before the fish goes into QT and is treated with antibiotics.

I’d look at polyp labs new reef safe ick stuff. It’s basically a peroxide. Not sure how they did thier trials. One of the warnings is it’ll start to kill off your microfauna and bacteria.
So yea,I think it’s like ozone and may kill the free swimmers.
The Soch Tate oxidizer (auto crrreact KILLING me) lol. Is a peroxide auto doser.

Speaking to Randy and Dr Bingham , yes it’ll def kill smaller organisms, but if your a microfauna and bio diversity fan, it’s not good. Side effect would be no pods sponges etc.
I’d assume a fish in poor health would also suffer.

Interesting application to velvet and isopods, but does it have potential as an antiseptic in fish?

H2o2 use as an antiseptic in warm blooded animals is unclear as catalase enzymes break down the peroxide very quickly, thus the bubbles on a cut.

Do fish have catalase enzyme as warmblooded animals Do? Curious...

Anyone ever tried Nogas treatment protocols for velvet or especially isopods? I ran into isopods on my last fish, would have been fun to try.
