    Love these Foam Rolls for wrapping and shipping things in! It is perforated every 12”, which makes things so much easier. Fast shipping, but it was Not delivered until A Month after it was ordered/shipped! Shame on the USPS! Not the Seller’s fault but they did issue a refund for me anyway, which I greatly appreciate. Highly recommend this seller!

    Not opened box yet, but looks as listed. Love fast Amazon Drop Shipping without having to Pay Amazon shipping cost, so saved with this seller. A win-win for me and the seller. I bought one of these before directly from Amazon with other items, so expect this to be same quality since identical. While not opened box yet, expect no issues. Very satisfied with this order.

    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
