I have a 12,000 gallon intex pool with SWG in Houston. The ph likes to stay in the 7.8 to 8.0 range. I can add acid and bring it down, but have to keep doing so or it will simply go back up. What are the negatives of keeping the ph in the 7.8 to 8.0 range? The water is clear and there is no irritation. Other than knowing the ph is high by testing I see/notice no difference in being at 7.2 vs 8.
