Works great
Very happy to be able to buy replacement solutions instead of having to purchase a whole new kit. I test the pool water frequently and mostly for chlorine and ph levels so I use a lot of these solutions in particular. They are accurate and work well.

PH and chlorine tester for pools
Add drops drops to your tester and it tells you if you’re chlorine and pH or too low or too high definitely lasts an entire season with many tests You will definitely need to have the plastic container tester to put the water in

The is for replenishing your kit chemicals
If you like your test kit, then all you need to do is get these replenishing chemicals so that you don't have to keep buying the entire test kit.

Not happy with this only because it really only measures total chlorine not free chlorine
Disappointed because it only really measures total chlorine. But the total chlorine and ph test results are pretty close to accurate. So not a total loss.
