My Taylor K-2005 rest kit arrived today. CYA is through the roof! I keep draining water and refilling, but I don’t seem to be making any progress. Pool is 3 years old. I’m only using liquid chlorine now. Started the season with granular shock which was my downfall.

I have a vinyl liner 18,000 gallon. Chlorine.

ph: 7.4
TA: 240 without the conversion for Cya
Free Chlorine: 4
Total Chlorine: 5
Combined: 1

I’m trying to refill with my hose. Would it be cost effective to have water delivered?

Thank you!
 
Ok, I( don't understand your reference to your TA having anything to do with your CYA??? :scratch:
Your CYA reading is how much stabilizer you have in the water.
Your TA is the Total Alkalinitu... a portion of your "Acid-Base" elements in the water. The pH is effected by the TA.

Did you get the necessary FAS-DPD powder test kit for FC/CC at higher levels? If so (K-2005 kit does not contain it) order it here--> FAS/DPD Chlorine Test Kit

Until I understand what your CYA level is, I can't comment on what to say about your water?

How do you know your CYA is through the roof? I don’t see it listed in your testing. I’m not even sure the K-2005 has a CYA test. Are you using test strips or pool store numbers for CYA? If so, don’t. Get the additional tests through this site or online through Taylor to test your own CYA. Total alkalinity has nothing to do with CYA.

Pretty common for pool store results to show adjusted alkalinity
