I'm having to replace my liner unexpectedly & will therefore have to start from scratch when the pool fills up. Prior to springing a leak, we had the water tested at the local store & the guy told us that our CYA was too high. He said to stop using chlorine tablets all together & just shock the pool 1x/wk. When we had a different pool guy come to look at the liner, he told us to get an automatic chlorinator. We've had issues in the past with chlorine burn on the liner from the shock too. I've read some of the posts on here about chlorinators & am wondering, what do most of you do for chlorinating your pool as regular maintenance? Will automatic chlorinators not help the CYA issue? Do you pour a gallon of liquid chlorine in 1x/wk? Any advice would be appreciated!
