Helping neighbor with pool

[jilted]

What about the CYA level? Should we try to gradually reduce it? They only need 1 more season out of this water before they get a new liner.

Your choice. They can run a pool with high CYA as long as they run high chlorine levels per the Best Guess Chart. Or, they can do a few partial drains and refills. But do NOT totally drain the pool.

EDIT --- Just went back and looked at your original post to find out the volume of this pool. They have a big pool. That would be a lot of wasted water to do drains. Since they are planning on replacing the liner next year, I think I'd just live with the high CYA if it were my pool.

I agree with Watermom. As you help them finish the algae battle ( lose almost no FC overnight and no CC ) start transitioning them to taking care of the pool themselves. Encourge them to start an account here and get a K-2006. They will be able to use the water they have this season - they'll need to run appropriately high FC levels for thier CYA, but no need to dump all that crystal clear water. Thanks for helping your neighbors.
