R-0013 CYA Reagent (8oz)



Eligible for FREE Shipping

NOTE: We are out of stock of 8 ounce bottles, so this item will temporarily ship as 4x 2oz bottles of R-0013. 4x 2oz bottles of R-0013 will still fit in the TF-100 kit the same way as the 8oz bottle.

This reagent is used in the test to determine your cyanuric acid (CYA) level. R-0013 CYA Reagent is mixed with an equal amount of pool water in the CYA mixing bottle. Then, the mixture is added to the CYA view tube until the black dot in the bottom of the tube is completely obscured. The required amount of the mixture determines the CYA level of your pool. The bottle contains 8 ounces, enough for around 16 tests.
