  1. Default Permanemtly Lower PH

    I just joined this forum two days ago. This is my first time going to the experts with a simple (?) question. My 55 gallon tank currently has Caribsea Aragonite substrate. This has maintained the PH at 8.0. What can I use to permanently lower the PH to 7.0? Without changing the substrate.

    Hate to say it, but nothing will make a change permanently, and try can actually harm the fish.

    Most effects of pH buffers eventually fade
    Everytime you do a water change you are adding a different pH water = stressing fish

    Why can't you change the substrate?

    Why do you want to lower your ph? What is the ph of your tap water before putting it in the tank? KH is what ultimately enables buffering capacity of ph in water. I don't understand why you want to lower your ph when you have aragonite in your tank which will bump your ph/Kh up automatically.

    Second that, no reliable and non risky way to lower it without removing the substrate. A ph of 8 isn't too high for most fish. They are more adaptable that most people realize. Stability is more important than achieving the ideal PH.
