 Easy to use titration test kitOct 14, 2008
By Jason Heiss
I wanted a titration based test for hardness (for better accuracy than the test strip kits) and this was one of the few I found. I checked a local pet store and they didn't have hardness tests at all. The instructions are very clear, explaining the types of hardness and how to conduct the test. I found it very easy to use, except that my water is so hard it was off the scale in the instructions! I think the scale goes up to 12 or 13 drops and I was around 22 before I got the color change. But you can fairly easily extrapolate the scale to higher values.

Great test kit for hardness testing in freshwater aquaria!Jan 22, 2011
By Randy J. Mercurio
I concur with all other reviews up until the date of this one. One reviewer seemed to give it 3 stars because of the awkwardness of the really long paper instructions. I can agree with this and my resolution was to cut off all languages I don't need! This reduces it by about half. Nothing else to say...it works and is well worth the investment.

Good enufApr 29, 2010
By Tyler Forge
"realist"
OK, firstly, there is no "laminated color card" regardless of what the product page says. This is one of those tests where you add drops one-by-one until there is a color change in the test tube. The number of drops indicates the water hardness. Really easy unless you aren't skilled at counting. For my tank water, I had to count all the way to 5.
So, my tap water is incredibly hard, but my crusty shower head already evidences that. My aquarium, however, is just fine. Cool.
I bought this test kit to supplement the test strips that I'd been using. Sometimes you simply lose faith and need a bit of affirmation. This test kit did affirm that the test strips are just fine.

Good testJul 26, 2010
By T. Franceschi
I don't have any other Hardness test so I cannot verify how accurate it is, but what I can say is that it seems to be accurate, as its readings always seemed to be compatible with the water in my tank; I have an african cichlid tank, which requires a very hard water; I test my water from the first day I have my tank, and as the cycling process occured, I saw the hardness rising a lot, due to interactions of my substrate and rockscape that are made of calcite and dolomite; I also have other API water tests, and I really like them;
