Do you have city water?Very interesting, thanks for the advice! Ill keep your suggestions in mind. With doing such big water changes, do you add anything special after a change? For example stress coat or melafix or anything like that. I'm always worried about my tap water. It's softened with salt so I'm never sure if my fish like the brand new tap water coming into the tank when I change my tank water.
If so, you probably have chlorine and/or chloramine.....very bad for fish. If this is the case, you need a dechlirinator such as Seachem Prime.
Do not add Melafix! It is not a water treatment.
I have welll water so I do not need to use any water
treatment.
I use a whole house water softening system so that's what my fish live in now
