Clorox Pool&Spa 3-Way Reagent Refills for Swimming Pool Water Testing, 1 Count, 0.5 fl oz

These are just the REFILL bottles of reagent test drops. There is no color chart included in the packaging at all. ... You must already have a kit that has the plastic clear test receptacle to fill with pool water, to then add the test drops to. Clorox is trying to get people to rely on their pool app, which now you must make an account for. The Clorox test kit with the paper test strips makes you more trapped into using their app, because you must take a photo of the strips with your phone. ... Sigh. The simplest of procedures, the corporations need to make more and more complicated, so they can make you a captive customer of more and more products and services you don't need.

This was one of the least expensive sets of Chlorine test chemicals I could find. Works great! I will order it again as it keeps me from having to spend an arm and a leg on chemical testing.

bought this thinking it was something special. I still have it. not the right stuff. too much trouble to return

save money, buy this. my local pool store wanted 22.95 for the taylor equivalent. F-that. This works perfectly well.

Good price, fast service.

EASY way to test pool chemicals. Got this as a refill for the kit i already have

I use the red phenol for science experiments and it works great.

its easy to use. gives an accurate reading.helps keep my pool clean and fresh . i really like using this kind.

Buy a set every year, great buy for the pool

Use 7 way strips one a week and this every other day. It always provides accurate results. Keep chlorine and PH/alkaline in spec and your pool will always look crystal clear.
