I just received the Taylor k-2006 test kit for a 12,500 gallon above ground, vinyl pool with SWG generator. Water is clear and beautiful. Not burning my eyes anymore. Test was performed at 9 AM when the SWG had been off for 16 hours. I'm concerned about water balance at the moment, not chlorine.
pH 7.6
Calcium hardness 120 ppm
total alkalinity 130 ppm
CYA 32
FC 1.5
combined chlorine 0 (but I used the smaller sample amount instead of the larger, more accurate amount & am not concerned about chlorine just now)
According to the test kit wheel, the saturation index is -0.1.
According to test kit booklet, I'm thinking I need to add a gallon of muriatic acid to bring total alkalinity down to about 80.
The booklet says 120 ppm calcium hardness is low, but TFP recommends 0-300 for a vinyl pool, so there's a conflict between the two recommendations.
I'll have to go purchase more CYA as I'm out. I am, however, surprised it is so low since I originally put in more than was called for but that was 4 weeks ago.
What's your opinion on these first test results?
