Our vinyl liner was just replaced last year in April and the CYA level is off the charts already. It measured at approx 120-130ppm.
How is this possible? I haven't added any stabilizer or other chemical that might raise it. Just bleach, soda ash (almost 30lbs to get pH right), clarifier and the dichlor that gets fed.
The only negative in my setup is a dichlor feeder and it's been feeding like crazy over the past week. Sucked up about 20lbs in 10 days.
I shocked with bleach thinking it just needed to be shocked and the chlorine level barely budged. I didn't think it could possibly be the CYA level but finally tested it yesterday.
Here's the setup: The feeder (Polaris Watermatic) is setup to pull through the drain plug in the filter pump and it gets fed right after the heater. So the chlorinated water is pushed through the filter then the heater before entering the pool. I am thinking this might be bad.
It has a water flow in the bottom compartment that allows the powder to dissolve before being fed. The chlorine level is tested by ORP.
I know dichlor adds CYA but this much in a years time? Could it be low-grade dichlor? I got it from Leslie's Pool.
Last time I had this high a reading it was after 5 years and I added stabilizer because I didn't know any better (pre-tfp).
Thanks
