pH is constantly creeping upward - even when there is zero pool activities. thinking this has to do with the climate in southeast florida here causing pH to naturally rise. what gives?
reasoning. given the air/climate in this region. average pH of saltwater is 8.1. would only make sense that all water around here want to equalize to 8.1.
