you definitely need cya, glad to see you added some. how is your cya dropping? or maybe it's just a testing difference (within normal limits).
Hmm, does the falling CYA and rising TA indicate large water losses? Might, I'd think, if fill water has high TA. How often are you refilling this pool?
New water last year and lots of splash out. Plus I lose 2-4 inches a week with evaporation.
It takes more than splash out to lower CYA from 30 to 10. Of course CYA measurements around 10 are suspect, as the reliable test only measures down to 20. If CYA really is 10, you have had a lot more water replacement than you just described. Do you have an auto fill system?
I am not sure the CYA was ever really 30... I have yet to see the dot actually disappear since our refill last year.
Nope.. no auto refill.
Nope.. no auto refill.
So, since you refilled last year, did you add Stablizer or Conditioner (with CYA) at that time or have you relied on the CYA in the pucks to give you CYA? If so, how many pucks are we talking about since then, 50 lbs, 25 lbs, 100 lbs?

So, in 25K gallons, that CYA alone should have gotten you to about 50. The pucks would have added more. Then you closed the pool, covered it, had a winter, and opened this year.
Did you add any CYA THIS year? I've read around here about pools that over winter have the FC go to 0, then the CYA goes to zero also. If the dot doesn't TOTALLY and ABSOLUTELY disappear in the test, then you keep adding to the test tube. You may have begun with no CYA.
It might be that you need to add 11 lbs again this year to get started off.
Also, in looking at the numbers, you really need to test more often! Now that it is time to swim, with CYA so low, you are probably getting 0 FC every day the sun shines on that water.
Where can i get a chart like that one? I see them on here but i can't seem to download them. would somone email me one like this one... [email protected]
