Yesterday I cleaned my tank (removed 15% of the water, vaccumed the gravel) and replaced the water with treated water (and Bullseye 7.0 since the tanks water was at about 7.0) after about 6-7 hours later I checked all the levels of ammonia, pH, nitrate, etc. Everything was okay. The pH was at about 7.1. Today, I checked the pH and such again, and everything was good. Suddenly, about 20minutes ago, all my fish darted to the surface and seem to be gasping for air, and the pH dropped to an astounding 6.0. What would cause this huge change of pH levels, and what is this pH doing to my fish, and the water?
