So, my pH in my tank has been chronically low since I’ve had it. When I got my axolotl, it was about 7-7.2. Then it dropped drastically to 6 (over the course of like a week) and now I have crushed coral in mesh bags to help keep it up, since it hasn’t raised on it’s own in the two months I’ve had my axi. Except when I do water changes (with conditioned tap water that is approx. 8 in pH) the already-7+ pH drops back to 6. Why is my medium-high pH plummeting back to 6 when I’m adding other high pH water into it?
