I’m about to commit hari kari here!!! We just completed a reverse osmosis treatment to help reduce nitrates because the pool was not holding chlorine. After the treatment, the nitrate levels came down, but they are still between around 50ppm.
The chemistry appears balanced.
7.4ph
102 Alk
30 Cya
204 Ca
58 phosphayes
500 TDS
Crystal clear water
Put one gallon of chlorine in a bit earlier (2 gallons last week) plus approx 4 lbs of granular (around 5 hours ago).
Test right now shows no chlorine
Nitrate test shows somewhere around 50ppm, maybe slightly higher, the test strip is difficult to interpret.
Any ideas what could be causing the chlorine to disappear so fast? Or what I can do to fix this problem?
