Waterbear,
Thank you so much for replying! I believe I’m doing the Taylor Salt triathlon correctly. Giving it a good swirl before each drop and stopping at the first point of color changing to salmon/brick red.
Pool is gunnite, 31,300 gallons, pebbletec finish.
More background info: I returned home from two weeks away on sunday July 9th and the pool had some algea. Chlorine was 0. I shocked the pool that night and took a sample to pool store on Monday AM.
Numbers:
free avail. Chlorine 4.09, PH 7.8, TA 103, CH 229, CA 5, Phosphates 3437!!!, Salt 1951, Saturation Index .4 ??
That day I tested salt on my cell 2500, on Taylor test 2600.
Step1 added 1/2gal muriatic acid, step 2 added 3 gallons of EZ Pour liquid Cyanuric acid which should take the CA to 30ppm. Step 3 added 80 lbs salt.
After this, my pool was measuring 2800 salt, PH 7.2, Next day I added additional 40lbs of salt and the reading has been bouncing around 2900 to 3200 on my SWG sensor. Currently reading 2900 and at the moment I’m not getting any errors on the SWG. (Happily). My pool builder recommends salt level at 2800-2900.
Earlier this month I had taken samples to two separate pool stores and both were measuring in the low 2000‘s. As mentioned - I chose to believe the combination of the Taylor and my pools readings. I don’t know how the pool stores are measuring the salt levels. The printout from one pool store says they have “ClearCare Expert Water Analysis System”. Could my pool be measuring incorrectly due to all the phosphates?
I’m going to take another sample to the Pool Store and pick up some aqua check salt test strips as well. (Never heard of them before)
Will report those numbers when I get back.
Thank you again!!!
