None of that is true that was told to you. Peroxide is a great algaecide, poor sanitizer. No loss of bacteria, or all these dosed tanks would spike ammonia. We dump huge amounts of it into full reef aquaria.
It is not indicated for treatment of columnaris, or any type of sanitization. Its a gargle, a very weak antiseptic but not strong enough to kill anything we can measure other than algae.
Sure you will get posts about 3% treatment causing an ammonia spike, but its just a one off observation like any other aspect of what we post. All other posts show no ammonia impact at a ratio of 99 to 1
This one guy set up a test tube of it in a lab, using vibrio, and peroxide killed it but it doesn't translate into anything we've shown in our multi year peroxide threads, with complex surface areas at play, tank variables vs test tube ones, the web is full of one off opinions about it.
The assumed effect on vibrio does not translate into filter bacteria so I say nbd. We continue to fix tanks with it, not sterilize them. I don't mean to imply if you wipe a kitchen counter, solid object, with peroxide and let it sit there untouched until it dissipates that no bacterial action has occurred. I'm just saying its poor compared to other actual sanitizers for the instance we are consider here, for columnaris in a tank.
Threads exist that show detailed peroxide work going on for years, thats a source of info about bacterial impact regarding peroxide in the aquarium.
Sure it could cure columnaris, its just not been shown to do that predictably like it does in other areas where it is amazingly predictable... If it works for you pls document the attempt well
