Just had my pool re-plastered about 1 month ago. Went with dark color quartz finish. Start-up pool guy did a great job and his 1 month startup service has been completed. I am now on my own for maintaining pool chemicals and chemistry. On pool service guy's last week (4th week) he stated Calcium Hardness was at 235. This was on Thursday. On Saturday, Leslie's tested water and Calcium Hardness was at 240. I also bought my own test kit. Today (Monday) i tested water and Calcium Hardness is now at 380. Leslie's also tested water today and confirmed Calcium Hardness is at 380. I am a little confused as to why the Calcium Hardness has gone up so quickly when water is just over a month old. Could i be getting false readings? Is there a certain time of the day to get the most accurate water chemistry readings? My pool start-up guy had said not to worry about the Calcium Hardness reading unless it went over 450 and that i would not have to drain and refill until the winter. Will i need to drain some water sooner to maintain Calcium Hardness within range and avoid possible calcium scaling on my new finish? Here are my water test readings as of today:
FC = 3
PH = 7.8
TA = 90
CA = 385
CYA = 50
Using 3 in. trichlor tabs in floater (part of startup pool guy's process). However, considering switching to liquid chlorine as primary source of sanitizer.
