Received TF-100 yesterday and started testing this am after previously using up some dichlor with the intent of actually seeing some chlorine and bringing up CYA(based on very low values of both per our pool store and test strips). As evident from the testing below, didn’t need the CYA, and we have decided to live with the slightly high level for now rather than replacing water. Based on the results below with the TF test kit, I am now starting a SLAM after adding Borax to address a low pH(from test strips and store, I believe the pH has been fine until the last 2 days and 8 cups of dichlor).
First result from TF-100:
Water: slightly hazy
FC: 1 (0.5?)
CC: 3.5
pH: 6.8
TA: 260
CH: 500(1000?-stopped at 40 drops, lavender color after 15-20 w/o further change-never blue)
CYA: 85 (maybe only 80)
After the above and the addition of 512 oz of 10% liquid chlorine and 325 oz of Borax, I obtained the following:
FC: 1.5
CC: 3
pH: 7.2
I then added 869 oz of 12.5% liquid chlorine and am off in moment to recheck the FC, CC, and pH, I hope to reach a FC of >30 and maintain it until SLAM complete. Meanwhile working on the TA by running the cleaner as my aerator.
We have an autocover that is closed about 90% of the time, so I expect that chlorine degradation by sunlight should be limited.
Input welcome.
