Make sure you are checking your pool water chemistry. These will tell you when you need to add different things.

I use it to test for filtering capacity of my water filter. Works great.

Slightly smaller than original bottles )20ml vs 22.5ml) but should still last for around 10 years.

Seems to work as it should. Always seem to run out of chlorine tester a half bottle sooner than the ph tester.

The red ph is way too weak and you can barely see the color in the water tester . I have used several brands in the past and this is by far the worst and unusable. Also amazon will not allow a return and instructs to contact the manufacturer website. And they do not/ have not responded after a week. DO NOT BUY!
