Easy to use and fast results! By Brandon on 9/15/2014Brandon would recommend this product to a friendI absolutely recommend this product. The instructions are very helpful but after the first couple of times of testing you won't need to use them. It gives you your readings in ppm (parts per million) but includes the conversion ratio on the instructions which converts to a very precise measurement of dkH.
Consistent & easy to use By Dylan on 7/31/2014Dylan would recommend this product to a friendTesting your alkalinity has never been easier. You can get an accurate reading in less than a minute. This product also gives you a consistent reading, just make sure your reagent has not expired.

Easy to use By Charles on 4/26/2014Charles would recommend this product to a friendI have been using the Hanna checker for 3 months now. I don't think I could ever go back to any other type of test kits. I love the repeat illite of the test results.

Awesome, Easy and Accurate...Consistent By JPB on 2/13/2014JPB would recommend this product to a friendEasy to use and very consistent results. For the first few months I double checked occasionally with a Salifert titration test...results very similar. Titration can be challenging to determine exact endpoint, especially if you rush it...not at issue with this test. :)

Good product By John on 2/1/2014John would recommend this product to a friendI am new to the hobby and found this checker very easy to use. None of my criticisms of the phosphate checker apply here - no problems with timeouts or reagent packets. The results are easy to read.
