Aquarium Advice FINatic
Whenever i do a PWC, once i add back the water the pH shoots down. My water i add is very acidic, but not as acidic as the tank is. Like when i test it, the ph vial is almost clear. How do i raise the pH? ive heard you can use Arm and Hammer baking soda, but that was from a petsmart employee, and the last time i went to petsmart, there were green chromis in the FW section...
