  1. Every time we use the spa a lot (like many time in a day or many people) the water turns cloudy and green while we use it. After a small shock, the water become clear. What can cause that???
  2. Let say I need 8 hours of filtration per day. Is it better to filter 1 time 8 hours, 2 time 4 hours, 4 time 2 hours or 8 time 1 hour?
  3. Are you trying to say that since temperature affects the CSI, it must affects the pH? But does it also affects the test accuracy? If the pH is affected by the temperature, then it would be important to test the pH immediatly after taking the sample. But does the test reading accurate at that temperature? If the test accuracy is affected by the temperature, then it would be important to test the pH after the sample has cool down. But does the sample pH now different at room temperature? I think it's very important to figure that out. Otherwise, what it worth fine tuneing the pH or the CSI. Or what it worth to use drop kit instead of test strips?
  4. I took two samples of water at the same time in two bottles. I put one bottle in the fridge and let the other one in the spa water. After about an hour, I mesured the pH of both sample: The cold sample had a pH of about 7.2 and the warm sample had a pH of about 7.8 Does the temperature affect the pH of the water or does it affect the test itseft?
  5. Hi, First, thanks for all the good info! As suggested here, I lowered my AT until I had a steady PH of 7.5 (It was 8.0 after filling my new/first spa last week). Problem is that my TA is now only 40. And if I try to augment it, my PH goes back up. With those numbers, I will need a CH over 400 to bring the CSI close to zero!. CH is currently around 100. What is the solution??? By the way, I'm using Bromine tablet and I didn't shock the water yet.
