So, going to walmart, in a little bit, to pick up my prescriptions, PetSmart is right next door. Going to get a new Nitrate test bottles, or should I just get the strips. Have never used them.
I honestly have no idea. Just a bit of a wild guess, but I initially wondered if it may have been caused by a sudden drastic shift in water parameters. Really hard to say excatly what is going on with that fish, other than we know a water quality issue seems to have been the initial cause of the problems.
