Hi Everyone,
I finally got a handle on my pool chemistry last year and realized my CYA was ~150. I managed this by maintaining a pretty high FC and that worked ok.
This year I am changing to SWG (good thing considering how hard it is to find bleach), so I think I should lower the CYA.
I live north of Pittsburgh in SW PA. The house was built on a former golf course and I live on top of a hill with the pool about 8 feet below the walk out basement. I have an in-ground vinyl pool built in 2010. I don't exactly know what the water table is like. It seems like there is not much soil and it becomes clay pretty quickly.
I have an auto-cover on the pool and I keep rainwater off of it with a submersible pump. I used to just have the hose for this out to the edge of the concrete patio (and utilized the weeping system to get rid of the water). I stopped that toward the end of last summer (after a particularly wet year) when I got a wrinkle in the vinyl on the floor of the shallow end -- the hose now runs to the edge of the property.
Obviously Exchanging water takes longer and uses more water than Drain and Refill, and is also probably harder to guestimate how long it needs to be done for, but doesn't run the risk of the liner moving or drying out or whatever.
How do I gauge the risk here? Should I just say "it is greater than zero, so just do an Exchange"?
