My dad said his PH was real low and asked what to do about it. I asked what his alk was, but he only has a really old HTH test kit for CL and PH. I tested it with my 6 way HTH kit and indeed his PH registers below 6.8, color definitely out of range. I then checked Alk, and the reagents are supposed to change from green to red when titrated, however, the green drops turn red without adding any of the second reagent. At first I thought I'd used the wrong drops, but nope. Checked the drops in municipal water and the are indeed green. Assume this means his alk is super low.
I added borax but this was before I knew the alk was so low and ph didn't budge. I'm making the assumption based on the Alk test that his alk is 0 (can't be though, right) and targeting 80 ppm will add the appropriate amount of baking soda this afternoon. Will let circulate and retest in a few hours (small pool with overpowered pump, lots of circulation).
Am I on the right track? I've never seen Alk or PH this low. He uses the people that installed his pool to open and close as well as trichlor pucks in an inline feeder. I had thought they might be the problem and still might be. I tried to get him to BBB but he's too lazy to buy bleach and manually add it. He also uses bag shock, I'm assuming dichlor so should have a small impact on PH, but I'll check. It's early in the season but I'm sure his CYA is already high, but I can't find my reagent to test, will require a more in depth search.
He has a heater. With PH this low, I told him to be on the lookout for green hair
