Here's the results of my first run for my Salt Water Pool. For each test, I did two and took the average to help even out volumetric errors of the amount of pool water taken and confirm results are accurate and tests were done correctly.
Results:
TC >10ppm (Deeper yellow than test kit gradations)
FC 12 ppm
CC 0 ppm
pH >8.2 (deeper red than test kit gradiations)
TA 130
CH 600 (tap water here is 250ppm)
CyA 38
Salt 3200 ppm by test, 3600 ppm by meter on the Hayward generator Should be around 3800 ppm
Calculated CSI 1.09 (using TFP Calculator)
Ideal:
FC 4-6 ppm
PH 7.2-7.8
TA 60-80
CH 350-450 for plaster
CYA 70-80
Salt 200-400 ppm ABOVE recommended optimum level
CSI -0.8
Temp 78F
Action:
Turn down SWG from 50% to 40% (done already)
Add 48oz of CyA Stabilizer (need to procure)
Re-test in a week and reanalyze needs.
Am I on track here? I know adding CyA will lower the FC but it is too high already so lowering production will certainly help. I really cannot hurt the water too much in a week and can adjust next week.
Going to the high end of acceptable CH requires a drain and re-fill of 25% of the pool with Calcium free water which isn't practicable because our water starts out at 250 PPM to begin with so this would really mean a complete drain and refill. We will have to live with the scaling we have until the next drain which will be in 2.5 years (Due to water restrictions we're allowed one pool fill every 5 years at tier 1 water rates. Going beyond tier 2 is astronomical and not practicable as there's really no health problem with higher calcium levels.
Where's a good place to get CyA? There's a Leslie's a few blocks from here or will I save a bundle ordering on line and then not be able to put it in until later in the week?
TIA
