We have recently purchased a home in Venice Florida that has a nice pool. The previous owner for 18 years maintained the pool himself. Since I am only there part time I have not choice but to use a pool service to maintain the pool when we're up north.
We were there for about 2 1/2 months and the pool has been great. The pool service works the pool every week and all has been well.
I had a couple free tests run by the local Leslies pool store and bought a simple kit and some strips to try to learn what the whole pool thing is about.
The CYA is around 100 or maybe a bit higher. I guess based on chemicals left behind that the owner used table in a auto chlorine system for years and thus
drove the CYA up over time. I have the service using only liquid chlorine now to prevent adding any more CYA to the mix.
I don't want to do a major drain, because we are going to be there for just a few days in May. But I'd like to start taking some action.
I'm considering a 15-20% drain (about 2000 of 12000 gallons) so that I can keep the chemistry under control since my daughter and the grand kids are coming
I'm hoping that that I can see an effect and then next winter I can run a couple more cycles and gradually reduce the CYA without getting into any
major chemistry cycling disasters.
I'm looking at a TFT100 test kit so I can see whats going on.
I did notice significant differances between a couple samples run at the pool store a couple days apart. since I'm an engineer I begin to doubt the whole
testing thing since they use similar test methods to those in the kits.
anyway.......Is this a viable plan?
Help for the newbie please.
