Plaster saltwater pool is about 9 months old. U can see my numbers below. In an attempt to cool water a bit a run bubblers 2 hours in the middle of the night. I also generate chlorine in three 2 hour intervals during the night. Then I run the pump (no chlorine) at a higher speed for an hour during day to help skimmers. My PH is bumping up .1 to .2 per day. I would like to drop alkalinity to 50 and allow ph to float around 7.4. But when the ph and alkalinity are this low CSI goes too negative. A pH of 7.8 bothers my eyes which is why I prefer 7.2. At this point I am strongly considering the Pentair Intellichem system to dose the muriatic acid as I am tired of adding 3-6oz every 3-4 days to keep Ph below 7.8. And when it gets to 7.8 it rises to 8.0 and above as fast as it when from 7.4 to 7.6. It never seems to hit a high level and stabilize. If it would sit at 7.8 I would learn to live with it but it doesn’t. It just keeps climbing even though alkalinity is at 70. Thoughts ideas something I have not thought of??
