Effects of high ph

Hi Reefcentral! I have always read to keep your ph between 8-8.5
My question is what are the effects of having a ph higher than 8.5?
My tanks goes up to 8.55 sometimes when I have to windows closed and the ac on.
Thanks Reefcentral

At some point, the pH will become dangerous to animals in the system. At what level that happens depends on what's in the tank, but a good goal is to keep the pH at 8.6 or lower. That should be easy in most cases provided that the tank has good aeration. 8.55 is not a problem.

Ok.
Thank you for the reply, Bertoni!
There seems to be a lot more information about low ph and not so much on high ph.

We don't have much in the way of data because it's much less common a problem. Generally, indoor air is high enough in carbon dioxide that low pH is more of an issue.

8.55 seems extremely high, I would check with multiple test kits before I believed that number

Yup, while maybe 8.5, that looks like a testing error without a scrubber and even that is pushing it.... get a second opinion

Yes, that's a good point. The measurement might be off. That's very common, as well. If you're worried, getting a second opinion might help.

Your pets will probably live but not thrive. Try to fix your ph.
