so my fish have been showing signs of fin rot for a few weeks now. I at first though water changes would be enough but sadly they aren’t. I do not have the money for medicine however I did hear you can treat with hydrogen peroxide. I have a few questions such as how much? Is it safe for tetras? Do I need to remove my media? Will it crash my cycle? How long should I do it for? And how often? Any help is appreciated.

I’ve heard a little about using hydrogen peroxide too, however I have not use it personally and don’t think I ever will. It’s typically used as a disinfectant for wounds and some fishkeepers use it to create a medical bath for their fish. I’m unsure of the dosage but if you look into it more then maybe you can find out the dosage and how long to keep the fish in there for.

I haven't used it, but it would definitely have to be diluted.
Personally would not do a treatment inside of the tank, rather in a sizeable container.

Yep i treat all my new bettas with it just as a precaution. Do a 50% water change, dose 1ml of 3% peroxide per gallon of tank. You can remove your filter media for 8 hours just to be safe but it never hurt my cycle. Dose every other day for a total of 3 trearments. If doing it in a separate container i would leave him in for 8-12 hours after that its broken down into water and oxygen. Kills algea too lol.

It might i never dealt with popeye though. It kills off any simple cell organism so external bacteria and algea are effected and not plants or fish. So the fungus it would definitely help with, popeye im not sure but it would be safe to try.

I am also trying to treat my betta for fin rot. I wanted to ask if I would keep on adding a new dose every other day to the tank or should i add new doses after doing water changes during the three treatments. this is my first betta fish so I'm still relatively knew to all this

Yes every other day you want to do a water change to remove the dissolved organics from the water and then redose.

That is great info from david1978

I use mblue for finrot, but h2o2 works the same apparently. I use mblue full strength on a qtip and swab/paint the fins or body topically (not close to the face tho). Works like a charm often with one treatment

I net the fish, place in top of glass canopy while fish is still in net, apply the swab and return fish to tank.
