What about the kN? The cement is hardly relevant here.

The tests for the KN will only arrive tomorrow.

pH and kH are closely related. You cannot raise pH without raising kH (alkaline buffer). Most likely, your kH is off the scale, or pH is being measured incorrectly.

KH, PH, magnesium, and calcium are very interdependent; one could say they are a whole. It's not enough to keep three components in balance; they all need to be together. If you're interested in understanding this, here it is.

What is the background made of? Only cement. What do you use to test the pH?

Sharon

Everything has normalized, pH is constantly 8.4 - 8.5. Thank God. I took measurements with a pH meter borrowed from Tim. Thank you all for the information - it will be useful.

So no one answered the fundamental question "what is the danger of increased pH?"

Karen

The livestock will perish. It can only live within certain pH limits.

At elevated pH levels, calcium ions are in a different state than at 8.3-8.4. In general, calcium precipitates. In short, for marine life (corals, fish, etc.), a pH of 8.3-8.4 is desirable and ideal.

Where is the information from? I'm really curious.

This is Chemistry. I can't say exactly where I read it, but I remember it. And I know for sure that there is a bit about it in the book by Ova-Savchuk "Reef Aquarium" starting from page 109. There is also some information on this topic in the section "Alkalinity."
