I've been lurking around for a few months as I've gotten into the swing of things with a new-to-me pool that came with a home purchase. I grew up always having pools so I sorta knew what I was getting in to, but having my own I really wanted to understand it.
I got a K2006 test kit and test PH and FC/CC often, and the whole suite once a week. I had a pool company open it first week of May as I was out of town and needed to get started, after which I had about 3" of foam on it and a CYA of 400+ (it would read 100 on my test kit with a 3:1 dilution). After multiple drains of about 18" down to enough where I started to fear for the liner and some rain I'm now down to a CYA of 100 (testing with a 1:1 dilution). I keep FC right now as close to 8 as I can and I haven't had any issues yet, hopefully I can get the CYA down further as the summer goes on. It would be easier if I could drain more water, but not willing to risk it.
Here's my current set of numbers:
Temp: 86F (it'll be 89-90 by late afternoon)
FC: 8.5
CC: .5 or less (using the 10ml sample) just barely gets some pink that one drop wipes out.
PH: 7.5
TA: 90
CH: 120
CYA: 100
The sand is about 4 years old from what I understand, same as the liner. Can't check it easily as it's hard plumbed, no unions. The valves for the skimmer and main drain were leaking tons of air through the handles so I've glue'd them up tight for now and will replace all that plumbing later in the year and do new sand at the same time.
