[AquaticLife] Big problem
Not to sound snide or patronizing, but this is what happens when you mess with your water chemistry. The pH of the water is held by a buffer, once this buffer is “broken”, the pH can drop precipitously. Thus far, you do not seem to be into too much trouble, other than the rapid shift in pH which may affect some fish. Adding the Rid-Ich+ is not going to be helping you. What you need to do is to make several 10-15% water changes over the next several days to bring your pH back up to more normal levels, slowly, so the fish are not shocked again by a rapid rise in pH.
FWIW, pH is not that important to most fish. They can tolerate a much wider variation that is often given in the books. When pH is important is with some species of fish, and you are not likely to find these at your local fish emporium, and, possibly, for successful breeding of your fish.
If you are going to place a lot of importance on your pH, then you should be choosing your fish based on the pH you have, rather than trying to make the pH suitable for the fish you want.
