Pool and Spa Test Strips Kit, 7 in 1, 7-Way, 100/Pack, Free and Total Chlorine, pH, Total Hardness, Total Alkalinity & CYA, eSeasongear TS107

I used these test strips year round for checking hot tub sanitation levels and I use about one bottle a month probably I bought about 10 bottles now and they work great. I used to use another name brand but these are so much cheaper.

Great price & good product !!!!!

They provide the information required to properly maintain our inground pool.

I compared these to my previous test strips and I got the same results. I test my pool water every other day so these were a good value for me.

Purchased for pool water testing. Accurate reading of pool chemicals. Avoid going to pool store who charge $20.00 for same product

Easy to use

I bought this mainly for the cyanuric acid test but it was not accurate at all for that.

I have 1 yr old strips from another seller and replace annually, also water tested. These strips barely work. Only edges getting colors and false too low readings. I will update review to show side by side other test strips that worked. Imagine no chlorine showing after 3hrs ago shocked with 8 lbs!!! Hopefully we can return. I did try them 3 x with same bad results.
