Got my test kit a few weeks ago and my pool has been humming along....
Got a few questions:
What causes the CYA to drop (what uses it up) I had to add some about 2 weeks ago to get it back up to 40, it had dropped to about 20 from 30 where it had been. How often should I be testing the CYA since it uses a large amount of the chemicals?
My CC is always .5 every week when I test is that OK or normal?
I've been keeping my FC between 2-4 it has spiked up as high as 5 and fallen to 0 on occasion (short periods of time) as I work to figure out how much bleach and how often to add it.
PH is staying between 7.3 and 7.6 this month. Right now my pH color is slightly different from the 7.5 mark, I'm not 100% sure if I am over or under 7.5 but I think under (more orange). I wish there was a test where you count drops of chemicals to get a more accurate reading.
TA has been between 100 - 130 currently 100 based on Mondays test which is down 20 from a week ago. Correction needed?
I was out of town last weekend so I turned my auto-chlorination system on to about 1.5, I turned it almost completely off on Monday, maybe .5 on the dial.
Recap of Mondays results:
Yesterday I tested and got these results:
FC - 0
Ph - 7.4
Water is clear and looks fine. Will check FC and PH again tonight and full test this weekend. I added some bleach last night to bring up the FC
