    When you test your tap water do u add declorinizer first then test the water? If not my ph from the tap is over 8.4 used an API Master test kit did a water change to the tank tested PH after it was 7.8 just tested it today and was under 7.4 in on day it droped .4 what would cause that? No Dritfwood. Added shells about 8 size of a silver dollar.
