I think doing what everyone says like opening windows and putting fresh air from outside into the skimmer is a good idea. In my tank I have a similar issue. I use kalkwasser and have a refugium on at night to fix it. I'm just happy with anything above 7.7 cuz I've read that it can make coral skeleton start to dissolve.
