@Galaxie 500 and @Newdude... what the heck are you talking about? did I miss something that connects your AC to CYA?
Now I’m worried. It’s 1:15 am and here I am. please please please tell me I didn’t just ruin a brand new $8k liner. We spent nearly $30k on that stinkin pool last year, when it was all added up. I just got quotes for a new ac (mine died of course) in the $18k-$25k range and I will probably throw up if we need to make any more large/expensive repairs to the pool.
Well sounds like you have multiple tests with 40ish.. so lets ride with that.. and that sounds perfect-ish. Lesson learned..is if you get a test result that is not expected.. test twice more to confirm.I have tested my water twice today (as often as my workday will allow) and my FC has stayed at 12. CYA was 40 both times (in between 30 and 40 actually, but I guess I should round up) so I’m not going to add anymore stabilizer. I think it’s fine, but I’ll keep testing it to make sure it doesn’t drop.
I’m thinking I just got a bad sample (one that had a high concentration of the acid that I just couldn’t see.)
This was my hope- u tested too soon & it wasn’t dispersed properly yet. High cya isn’t the end of the world but it definitely complicates things & adds to the empty bleach bottle count. Continue Slamming for 40ppm cya so fc of 16. Just to be clear no one is trying to be ugly or accusatory when asking questions- just trying to get all the pieces of the puzzle so we don’t lead u astray due to missing information. Also of note.. if you’re using PoolMath & are keeping logs you can toggle on sharing in the settings & make them visible w/your profile to the forum. This helps us solve mysteries as well as keeps you from having to try to explain / remember every addition you’ve made.I have tested my water twice today (as often as my workday will allow) and my FC has stayed at 12.

Yes, I have these. It’s how I learned to do the test bc “till the dot disappears” just didn’t make sense. My water was always clear, no turbidity, so I used the samples and THEN I got it.75 CYA would be higher than ideal CYA count if that’s what yours really is.
CYA reading is the hardest test to get a solid confidence with. Repetition by testing over time will help you with that (practice makes perfect).
The place that sells the TF 100 test kit also sells pre-calibrated bottles of test water for various things such as CYA. In other words you can buy their water with a specific amt of cya already in it to test against with your kit at home.
Just as a word of caution on the standard solutions, they are not always that accurate. At the beginning of this season I had some issues with my CYA test results showing less than testable amounts of CYA. So I ordered the standard solution to improve my testing skills and confirm my reagent was good. It tested the same as my pool water, less than 30. After some process of elimination I determine it was the standard that was no good. Dosing the pool with CYA and recent tests confirmed that finding. People much more knowledgeable than me advised me accurate standard solutions are very difficult and expensive to produce. TFTestkits at least refunded me my cost, and I learned I won’t order standard solutions again. My advice, proceed with caution using standard solutions.The place that sells the TF 100 test kit also sells pre-calibrated bottles of test water for various things such as CYA.

I actually found that my test solution was a little off. It was supposed to be 50ppm and I found it tested at 30. However, I got to see the turbidity, which I wasn’t getting with my pool water. My pool water was just clear every time so I really couldn’t fathom how the dot would disappear.Just as a word of caution on the standard solutions, they are not always that accurate.

And room temperature or above right?CYA test is done outside back to sun, tube at waist. Not indoors.
Is this a joke?And room temperature or above right?
I thought I read somewhere it was preferable to do the water tests indoors? The lighting is certainly more consistent inside...CYA test is done outside back to sun, tube at waist. Not indoors.
Not a joke. Temperature can impact the CYA test turbidity. If the water is below ~70F it can impact the result.Is this a joke?
Aah. ~70F makes more sense than “room temp” which, seemed weird cuz my pool is outside, not in a room. But yeah, ~70 is about what I imagine a glass of water on my counter would be.Not a joke. Temperature can impact the CYA test turbidity. If the water is below ~70F it can impact the result.
