New owner with high TA

[Dana8333]

First test complete but I think I did something wrong , this is new fill from tap water ( city water ) 8650 gal pool vinyl liner
Using TF-100 test kit
TC 0
PH 8.2
FC 0
TA 680
CYA 0

So I know I must address CYA first but is my TA way wrong ? Looks off the chart to me . What do I do about it ?
Thanks for your help

Welcome to the forum! Great job on getting a quality test kit!

For TA testing - review the following for the first few tests:

Sometimes a static electric charge can build up on the R-0009 dropper bottle tip, causing the drops to be smaller than usual and making the test read higher than actual. You can prevent this by wiping the tip of the dropper bottle with a damp cloth or tissue before you start and after each drop.


I suggest you read ABC's of Pool Water Chemistry.

Please add 3 ppm FC worth of liquid chlorine now. Get 30 ppm CYA granules dissolving. Add chlorine daily to maintain your target range for the 30 ppm CYA - see FC/CYA Levels
