    BEWARE OF THIS SELLER!!! Does not honor posted price. I bought 2 @ 29.99. Seller was very responsive during order process. Item was marked shipped but no tracking info. Seller responded that the package was shipped but no tracking. Days later, Fedex msg me that a package was enroute, I checked purchases, and tracking was showing. I was then notified via FedEx and ebay that my package was delivered. NOT TRUE!!! Seller has relisted the same items for 94.99. Refund issued.8(

    Reliable Test of KH & GH

    Easy to use test to stay on top of aquarium KH and GH levels. Fill the test tube to the level mark with aquarium water and add the solution drop by drop until the desired color change occurs. It is pretty easy to see the color change against a white background. The hardest part is filling the test tube to the line. I use a straw to lift water from a small cup of aquarium water - much easier to control it that way.

    very complicated to use .

    I have had aquariums all my life , used many tester kits in the past, I do not like this one , too difficult to use , counting drops and then if the color is not correct adding more drops ? I never get any results , took a water sample to pet smart and tested and all was good, could not get results from this testing kit. my suggestion , do not buy this kit.

    Great kit even for other use.

    I actually got this kit, not for aquarium use, but for checking the GH (general hardness) for setting up a water softener. I had an issue with mine running out of soft water. This lets me check to make sure everything is set right and working correctly. Very accurate and precise measurement, since it uses a chemical & dropper to check with. Accuracy you'll never get with a test strip. I can't comment on the carbonate part with this kit, since I don't need it. Highly recommended.

    A reliable way to know your GH and KH measurements

    Reliable and easy to use and read. A quick, reliable way to measure your GH and KH. I have shrimp so it's essential to know these readings. Trustworthy product and highly recommended by other fish keepers.

    Very useful not only for aquarium

    I was able to check the hardness of the water in the faucet and after the filter Brita. Very useful to know this parameter for watering flowers and taking care of a washing machine and dishwasher
