Comments: The kit is good overall, the color change is spot on and easy to read. The bottle leaks so some drops my stray when turning the bottle over to drop into the vial. Once the first drop leaks out, the others are a little easier to manage.

Comments: Reliable product testing results through the course of each bottle, and from bottle to bottle. Easy to use.

Comments: Alk is really important in a reef tank. Especially an SPS dominated tank. Low or swinging Alk can cause poor colors. This is an easy to use test kit so it makes the chore of testing your Alkalinity easy.

Comments: SUPER easy test. I normally use the Elos but since I lost my job I have to save money where I can so I tried this and I will be staying with it, even when I get a job. Color changes are instant and extremely east to see. The change from green to red is as drastic as a stoplight.

Comments: This test kit is incredibly easy to use but it only measure DKH in increments of 1.0 DKH.
<br />This would be perfect of they let you measure DKH in increments of at least 0.5 to ensure a more accurate reading.

Comments: Well my problem wasent that my alk was bad, my problem was that I have 2 other alk test kits that gave me two way different reading so I used this one to see which one was right.

Comments: Love this test kit. Easy to use and fairly accurate when doubling the sample.

Comments: very happy with this test kit.

Comments: Exceedingly simple to use. Simple one step titration. I really like that you easily double your testing sample and adjust the interpretation of your results accordingly to get a more precise reading.
