    Best Methods/Products 4 PH, Alkalinity, KH, GH

    If you have to increase the PH, KH/Alkalinity and GH, what are your favorite methods and/or products for doing it? I hear about coral, limestone and chemicals and want to know the best way to change parameters but I'm worried about it all fluctuating. My PH is just over 7 and my water is soft.

    GH? growth hormone? Are you saying you're just over 7 in your tank? What's your alkalinity at?

    GH is general hardness and is more for FW.

    are you using RODI??

    what salt??

    do you maintain Ca and Alk?

    Can you post your parms??

    IMO a good quality salt and water changes should maintain your pH and Alk. when i have to raise my Alk i use baking soda, it will raise your pH too but i think you should tell us some more about your system so we can maybe fin d the cause rather than just try to cover it up.
