It's 7.5 at lights out and 7.6 during the day. Is it a problem and how do I bring it up without affecting my other water parameters? Thanks

start using kalk for your calcium and alk needs or used baked baking soda for you alk needs. Both will raise your ph.

I have been following this thread as I have the same problem as well. I use "baked" baking soda for kh, but maybe I will try kalk and see if it makes a difference

Dont mess with it ph probes are recommended changing 6 months to a year and much sooner if exposed to air. I would go with the test kit. My probe ready 7.6 and elos test kit reads 8.3.

What's an idea pH for soft coral typically?

Honestly, unless something in your tank is causing you to think that there is a problem then you don't have a problem. Don't mess with it unless the condition of your livestock would warrant it. Most people here never even bother to check it. Me included, never had a clue what my ph was for over 2 years until I bought a controller that had a ph probe.

Thanks guys. I do run a kalk reactor and a calcium reactor. Both the Ca and Kh are both in check and I did'nt want to screw them up. There is nothing that is looking bad but noticed everyones Ph is 8.2. I got the answer that I wanted so I will leave it alone.
