Okay, pool was new in July 2015. After 1 month, they added salt, and I have a Pentair IC40 swg.
We check salt levels weekly, using Taylor kit, and it bounces between 3800 and 4200 last week 4200 after 3 months. We've not added salt since conversion in August, going on 3 months now.
Past 3-4 weeks, Cl level has been dropping. I've bumped % from 20% to 60%, adjusted run time longer, all to no avail.
Manual says to check for cleaning every 3 months, pulled out of unions, plates are completely clear. Hooked back up, all green lights on indicators.
Poolmath says to run at Cl of 6, yesterday it was 3. Been adding bleach almost daily, 4-5 times a week.
We've had a crystal clear pool since day 1, we've never shocked or SLAM the pool, as chemical results didn't show a need.
Is our salt usage normal? Should we go 3 months without adding any, and have test results show differing readings?
Thanks much
