Hi. Does it seem possible to lose 45 CYA in a year? I only recorded backwashing my pool twice in a year, so that was likely (and hopefully) wrong. Let's say I backwashed 5 times, though. I still wouldn't loose more than half of the CYA if I'm just emptying an inch or 2 of h20 out of the pool if the only way to get rid of CYA is by emptying water, correct?
The other reasons for discrepancies could be
1. my testing a year ago was not correct (but I did add the amount of stabilizer I added and recorded it-maybe 8 lbs if I recall correctly-I have it written in the app)
2. could my 3 bottles of r0013 all be bad? I bought a new TF-100 kit and that new bottle of r0013 doesn't have an exp date, neither does the one from last year. I tested with all 3 bottles a couple of times throughout this process of getting my pool ready for the summer and then I threw out the old bottle. I have a larger bottle that expires in June that I'm also using.
I've added about 5 lbs of stabilizer trying to increase my cya numbers and I'm pretty nervous about it. I still have some stabilizer in a sock in the skimmer and am thinking I'll take it out until I get some replies here.
I'm also nervous cuz Leslies said I had 57 the other day before adding an extra 3 lbs.
I didn't measure exactly how much I added because I made the mistake of doing it over the skimmer and getting it wet immediately (twice).
I know I"m not supposed to trust the pool store's readings but my readings have also been all over the place.
I measured 50 cya. I added 46 oz and then measured 20, then 30, then 35-different days/times of day/bottles of r0013, but somexs measuring 2 or 3 xs between bottles to try to see if they were both the same.
I'm also doing a SLAM, which I don't believe would effect the CYA reading.
If u are able to provide any feedback that would be greatly appreciated. Proavia's gonna tell me I should've had this right by now.
thanks!
