Hi all - I took over managing my pool from our pool company one week ago. Their “readings report” has been saying chlorine (not sure if free or combined) greater than 5 and they never test CYA. They have been using trichlor tablets weekly and occasionally liquid bleach. I know all the dangers of trichlor tablets but because I work a lot (like many folks here!) and have a 6 month old baby to keep tabs on I decided to keep the trichlor going for now. Adding bleach daily didn’t seem feasible for my schedule but I’m open to it. My free chlorine has gone down over the last week with one 3 inch trichlor tablet in the chlorinator from FC of 2, to 1.0ppm yesterday. When I got the 1.0ppm reading yesterday I added another trichlor tablet to the chlorinator and today I have these readings.
FC- 0.5ppm
pH- 7.7
TA - 110
CH - 475
CYA - 110 (it’s just below the 100 line on the cylinder)
My water is crystal clear. What is the next step to raise the chlorine? I’ve read SLAM only necessary if pool is green? Is the high CYA causing my chlorine to drop? How rapidly do I need to get the chlorine up?
Appreciate any and all help!
