I recently installed a SWCG, and it's doing a good job of maintaining FC levels, however I am seeing a faster rise in pH now. pH rose to 8, so I added muriatic acid to drop it back to 7.6. About a week later it's back at 8 again. I am only running the VS pump at 1750rpm for 7 hours a day, so I didn't expect to get much rise due to aeration, but this appears to be a thing now. Before adding the SWCG and VS pump, I ran the SS pump full speed about 5 hours a day and didn't see this issue with pH rising so quickly...I only had to add acid once over the summer. I just added muriatic again to get it back down to 7.4 and now I am considering adding borates to buffer the pH through the winter (Houston, so the pool stays open so I can use the spa). I also recently saw my CC increase to 2,0, which I haven't seen ever since I started following TFP methods in the spring. CYA is 75. It's been raining and leaves are dropping so that's a contributing factor (and I empty the leaves from my robot every few days) So I am working two problems at once, but I think the sequence/priority matters. The plan is to:
- Address the CC problem first by doing a SLAM.
- Once I bring the FC levels back down under 10ppm, move the pH to 7.4 and then add borates to buffer the pH rise going forward.
