Wednesday, June 1st 6 a.m. - Day 7

Our pool continues to become clearer (by looks anyway), with still some debris laying on the bottom. Yesterday’s results were basically a repeat of Monday, except with testing spread out to every 3-4 hrs with a total of 14.34 gallons of chlorine (bleach 6%) added. Again the FC level did vary a little more during noon / afternoon hours and the CC level stayed basically the same (0.75 – 0.5 ppm). Overnight the FC level did drop by 1 ppm (maybe due to testing?) and the CC level remained unchanged (0.75 ppm) – which prompted a question as to why no change since Monday’s p.m. test? I contacted Taylor and asked them if there was a procedure to test the CC level independent of FC, using a 25 ml water sample (0.2ppm resolution)? The answer I received back was “Taylor does not currently offer a method for testing combined chlorine independent of the free chlorine result. To my knowledge, I am not familiar with another company that does.” - which seems a bit odd to me? Does anyone on the forum have any comments or concerns about their reply?

With all of the repeated testing, I need to immediately re-order the reagents for the chlorine testing! So plans are to do the dosages of chlorine (bleach 6%) - based on my records from the past 2 days, and only test 2-3 times / day, especially for 8 p.m. today & 6 a.m. tomorrow.

Watermom!
I do agree with your recommendation, another day to see if the CC will ever go to lower? Thank you for your response & have a great June 1st!
