Clorox® Pool&Spa™ Swimming Pool 3-Way Water Test Kit, Accurately Measures Bromine, Chlorine and pH Levels (Pack of 1)

These are 1 oz. bottles, which are twice as big as most kits have, therefore twice as many tests for dollar spent.

This test kit is the best of a few I have had. Easy to use. Bottles dispense easily and accurately. Colors easy to match the color panel. The single cap is easy to handle. This is the one to purchase.

This appears to be identical to the Taylor K-1000, but at a reduced cost. Wouldn't be surprised if this was made by Taylor. I always found the colors easier to read on this versus some other styles/brands of test kits.

Simple to use for basic pool chemistry. The price is unbeatable.

I trust the accuracy of this test kit more than test strips, but being able to distinguish between the colors in this unit is difficult, to the point of guessing while holding it up to different light sources to be certain which range it matches. At least with test strips, the differences in colors are easier to perceive, even if they can be notoriously inaccurate compared to test kits such as this one. The price, however, was certainly reasonable.

Very good, excellent Very working

The case keeps everything neat. The color gradient is easy to read. Fill with water five drops in each side and you are done.

I've tried others but these are the best. The colors are accurate, the bottles dispense a single drop easily and precisely. The cap is a single piece design which makes it convenient and easier to empty and clean over the two cap design. Expiry date was awesome also, +16 months, plenty for my pool season. Note: I didn't use the app.
