Im no expert but seems a lot of PH low issues are related to the amount of disolved CO2 in the water especially during the months when the windows are closed. Im in the same boat right now and I am looking at putting in a CO2 scrubber from BRS. Another option is if your skimmer is close to a wall or window is to vent your skimmer intake outside but it would need to be a short run.
