I live in Austin, Texas and like nearly everywhere, we have been plunged into winter early. While we don't need to winterize our pools, I do need to do a winter change over, and this year, since I added an acid doser, I have some options which I am seeking some direction.
During the season, I have SWG which handle my Cl generation, and to combat the pH drift that it and my spa spillover creates, I added a Stenner acid doser. Everything has harmony!
Now my pool water temps are in to low 60's, the SWG is turned off. Here's my plan:
1. Add floater and pucks to maintain Cl (currently, my CA=40 and I can use this method to maintain Cl and raise CA to 80).
2. Adjust the acid doser down to maintain pH=7.3 (a bit lower due to CH=400).
3. Once CA=80, clean doser and switch from acid to Cl - dial it in to maintain Cl=2-3. Manually maintain MA
4. In the spring when temps hit 65+, switch everything back over to "summer mode".
Is this a sound strategy? The other alternative I see is to skip pucks and go directly to #3 and manually add CA. I have both pucks and conditioner.
very high copper in refill water so using Jacks Purple to try and mitigate (sequest = 6ppm - adding today to get to 12).
