    I bought one of these test kits. it is the only freshwater K test kit I found. It is the only one in the proper range as well. The first one didn't seem to work right. It was backwards from what the color card said. On the card, 0 K gives a dark brown and high K gives clear or light yellow. After various tests on tap and tank water with and without K added It seemed backwards so I contacted them and they sent me a new kit.


    I received a lot of free goodies and 2 brand new K test Kits from Easy Life.


    The seals were broken on one which I assume they tried it themselves before sending it out to replace a bad kit. So I assume it worked right for them. I used that same one.


    I ran the following tests:


    Tested tank water, got bright yellow color. Perhaps 17 ppm according to chart which only shows a weak yellow as an option.


    Tested sink water dechlorinated with activated carbon block filter. Same 17 ppm. Suspicious but possible.


    Tested RODI water and got darker color. About 5 ppm at best. Should have been 0 ppm but I would accept is as close enough. it would be OK as long as I know that is what happens at 0 ppm.


    Tested RODI with 2 drops of Flourish Potassium Added to the 2 ml sample of tank water. Should have been clear but got light green color. I am sure it is just too much for the test to read properly. Lot's of color test malfunction at overdose levels.


    I decided that so much K was probably throwing off the test and causing the green color. I decided to add some K to my tank then retests. I used 5 ml of Flourish Potassium to about 15 gal of actual water. I let it stir for 20 minutes with the pumps. I retested.


    Before I got a bright yellow color. This time I should have got very clear. I got the yellow color again but it was slightly more clear.


    I conclude that the chemicals are actually working this time. I just think the color card isn't very good. I supposed a person could make some standard K solutions to use instead. I think the test would be accurate with that method. Making all those Potassium standards is a pain though. A person could could probably make there own color chart of they did go to all the trouble of making the standards.


    I have asked the company to advise me if there are any ions that might be causing interference or if my method is wrong. I am following the instructions of course.


    I would like to say that even though the color card sucks this company has gone through great lengths to try to make me happy. When I advised them of the problem they shipped out a new kit immediately. They are in The Netherlands and I am in the US. It came back so they reshipped with a different carrier. It came back to them again. They shipped a 3rd time with upgraded service and it finally got through. They gave me some nice bottles of ferts and liquid Carbon. They gave me 2 replacement K test kits as well. They have been good at answering my email. All this must have been a lot more then what I paid for the Kit so I am not asking for a refund. I am happy with what they did for me. I hope they get the color card worked out. For those of you who really want a working K test for your planted tank I would still buy this product if I had the skills to make standard solutions and a color card. It would be cheaper then a 200$ colorimeter etc. You could also just eyeball it and know about where you were. Close enough is good enough with K. Just to tell you weather you had any K in your water or not.

    Thanks for the review. I've been looking to buy one in the US but couldn't find any retailer. Where did you get yours from?

    I looked everywhere but I can't find it or remember. I do remember it was a pain and that is the only US distributor. That kit was bad so maybe you should deal with the home office in The Netherlands directly. That is where I got the good kit from. Try this email: support@easylife.nl Maybe they can direct you.I have an extra kit that I never opened. They might have to test it before shipping because of the issues. PM me if you can't acquire a kit.

    Lamotta and Hanna both make a K+ test kit. Hanna makes a colorimeter that's somewhat reasonable.

    I inquired at Hanna. The colorimeter was 200$. This kit was 30$ so I went with it. Never tried LaMotte or Hack.

    Yeah, $200 is not exactly reasonable... :p I wonder if these colorimeters can be programed for any other nutrient, not just one. Seems like a waste if it can't.

    Hanna offers a wide range of this type of product. They do offer a all in one model but it costs around 800$ without all the chemical reagents you need to run the tests. Only works in Fresh water. If they ever make one that does both I think it might be worth it.

    You can DIY the reagents if you run a lot of test. FEW aquarist do however. The test kit sits in their closet mostly after a few test.


    Most test kits have such lives. pH meters, not so much, a decent KH test kit, not so much.


    The K+ measurement is tubimetric, and it is not aprticularly useful or needed for aquarist.


    It's very easy to do a water change and add K2SO4 or other salts to get a ppm range and keep it there.


    Folks just have few practical reasons to measure it.


    Marine water has about 390 ppm of K+. Most FW test kits will have issues with such a high range and then .....a low range used in FW systems. You also have interfering ions in marine water.

    I mostly just like to try out new things. I'm a sucker for numbers and new test kits :) I don't supposes you want to reveal the secret ingredients of any of the test kit reagents do you? I have always wondered what was in the nitrate, phosphate, and Potassium tests. I did DL a manual from the EPA but haven't been sure if it was the right kind of test or not.
