Great forum, been lurking for a bit.
I have a pool that's almost 2 years old, have gotten somewhat lucky that I am just starting to have issues using trichlor tabs. Yes, planning to stop using them. Have never replaced water either.
Major issue is that I work and stay out of town all week and cannot switch to daily liquid chlorine dosing and testing very easily... No SWG in the plans with a travertine deck either.
That issue will have to be dealt with at a later date.
In the meantime, I'm looking for where to start to begin to get the water in better shape before I drain water to reduce the super high CYA level this winter. It's finally cooling down here, so that will help require less chlorine.
Can I over-chlorinate to not have to test it every day after I get an idea how much chlorine loss I see per day? I am planning to be home for about 5 days straight later this coming week. Maybe then I can have someone add a set amount daily to keep up the FC level.
Thanks for any assistance. Here are the numbers I got today using my new K-2006C test kit.
I will add liquid chlorine to raise the FC to at least 4 (or higher?) later tonight or early tomorrow based on suggestions. I do understand that FC is way too low especially given the CYA level. Just can't bring myself to toss more tabs in there.
