    Sounds like carbon dioxide buildup. Have you closed off any doors or windows that are normally open? Any pumps or skimmer malfunction? Anything change that would affect water flow or oxygenation?

    I think you hit it on the head, my pump died on skimmer 3 days ago. Ordered a new one it just came in the mail today, PH is up to 7.8 but everything is ridiculously stressed.

    Just placed a second ordre for a back up pump too.
