Just one drip to read 4 critical pool water levels. Test for chlorine, ph, cyanuric acid and total alkalinity, all with one test!
The AquaChek Yellow Strip is best for chlorine sanitized swimming pools. Simply insert the 4 in 1 test strip into your swimming pool or hot tub water. Leave it in for about a second, and then promptly remove it. After a few seconds, your results will appear! Each packet comes with 50 test strips.
Keep your pool water clean and clear by testing your pool water at each end, at least two times a week.
To keep your hot tub at its best, test your spa before each and every use.
We recommend recording your results so you can better track any changes.
