So I tried again today and I still get 70 ppm with the sun at my back, waist level and if I turn into the sun and add more light, 60 ppm...with the R-7065.
My own water comes back around 35 ish...which is inline with what I expect from the amount I added although I expected it to be more like 40 ppm.
Since it is Saturday, I ran a full suite of tests:
FC 5
CC 0
pH 7.5 - 7.8
TA 90
CH 220
CYA 35
Days Since Water Filled Due to New Pebble Sheen Refinish 37
