I feel like an idiot, but I thought I should post my experience whether or not things are said about my stupidity.
I decided today to dose H2O2 as I have been trying to rid my tank of several algae types. I thought a 10ml per gallon "bath" was my way to go. So, no I didn't read through the whole thread before I attempted this. Today is my 50% WC day. After I removed the water, I added the peroxide. Was going to let it sit for an hour, but after about 30 min I noticed my fish were coming up a lot to get air (cory and oto), and a group of them were breathing at the surface (rasbora and neon). I promptly added my prime and then refilled the tank. I had to leave and was gone for a few hours. Came home to 4 dead rasbora, one dead neon, and I have lost 2 otos. I have other otos that are almost out of the tank, sliding up and out of the tank at the water level. I have them now in my QT tank and I performed another 50% wc.
I would rather live with algae than kill my fish. So far, all of the cory are ok. They have still been coming up for air, there are bubbles in the water, tiny ones. Not sure if that is CO2 or H2O2, as my plants are pearling from the water change.
Please don't be an idiot like me
