Okay, I'll just fill you in a bit: I have a prescription of -0.25, and already have one pair of glasses, but would like another, and was wondering if you can actually buy glasses for such a small error in drugstores (because they'd be cheaper there).
I did a water change about a week ago before I added 3 balloon mollies. I did another today and just tested the water and the ammonia is at 0.25ppm, the nitrates and nitrites are at 0ppm. will the fish be okay til tomorrow til I do another water change? Or is there something I should do tonight...
