My pool is about 8 months old and i constantly find my PH rising. I live in Houston, TX and the outside Temps are about 95 -100. I feel like my numbers are all in line but don't really know why it doesn't seem to want to stabilize. I thought it would stabilize by now as i would like to keep the PH in the range around 7.2 and 7.4 for my CSI to be balanced. I can get it there by adding acid but then it seems to drift up in the next day or two. I am using liquid chlorine and not chlorine pucks. I do have a waterfall which i never run and i do have a hot tub which has a spillover into the pool which i thought may be contributing to this PH rise due to aeration. I have a good Taylor K-2006c test kit and test CL and PH every day in the evenings. Any advise or tips would be greatly appreciated.
Outside Temp 98
Pool Temp 94
