I'm a lurker, posting for the first time.
We've been in this house for 5 years. I think the IG pool is 8-10yo. For the past three years I've done everything except closing myself.
I've used our local store for tests and chemicals. I've fought PH and FC and algae every week.
Some pool info; IG, 25000 gal., vinyl liner,
The water looks great. The kids wear googles, no one complains yet of irritated eyes.
Today my Taylor K-2006 kit arrived. I've read Pool School, still don't really understand much
If my tests are correct, these numbers seem wacky...
It looks like I need to drain and replace 60% of the water ?
Our liner is very wrinkled, pulling away from the corners. I know we're due for a liner replacement.
I was hoping to delay the liner for another season or two. I'm afraid of totally ruining the liner if I do a
big drain and refill all at once. Backwashing / draining a couple inches a week and refilling from our well seems
safer for the liner. Although I hate adding well water, it's hard and has high iron.
I've never seen a real 'order of operations', as far as finding balanced water.
Should my priority belowering the CYA or raising the PH ?
I've many questions I'll save for later.
