I've got a spare sponge filter in my 90gal that I'll need to borrow for my 20gal. The water I use in the 90 gallon is 6.6 pH, and around 35 ppm hardness. The water from my 20gal is at or over 8.0 (I've got a high range pH test coming, but the normal range has always shown 8), and somewhere at or over 140 ppm hardness (I tested it a while back, 140 was the highest number the test could offer. I'm guessing it's at least close).
Will the sudden change in water parameters shock the bacteria, or will it be okay?
