First the Pool Store story:
My neighbor just got an in ground pool built, and I've been suggesting him to follow the TFP approach, get a good test kit, and learn how to maintain chemistry. I suggested an SWG, as I've been very happy with mine.
About a week after his start up, I went over to check it out, and he had chlorine pucks in his skimmer. He said the pool store told him that even with the SWG, he still needed to put chlorine (Trichlor) into the skimmer! I got my test kit, and his chlorine was 16.5! His CYA is 70, so 16.5 chlorine is over triple the recommended level. He shut off his SWG for a few days, and brought it down.
My question is about Total Alkalinity level. He has an Eco Finish Aqua Bright pool surface:
Their startup/maintenance guide recommends TA 120-150. This is a lot higher than I've ever seen recommended, and I wanted to know if anyone has experience with this, and knows if this makes sense. Will TA that high cause any other problems?
