NT Labs Pond Lab Multi Test Kit (All-in-one Water Testing Kit - Ammonia, Nitrite, Nitrate, pH, General Hardness (GH) and Carbonate Hardness (KH)), Accurate Results, Easy to Use (Up to 200 Tests)

No way to tell how acurate the results are but enjoyed playing with the kit. Used to test out door pond as fish had been missing for acouple of weeks, also got a bubble stone to help oxygenate. Tests came back as safe, fish have been seen, feeding and seem all well, looks like the were just hiding, new pond so looks like they were a bit nervous till they got used to it. Next checking if the ph varies wildly over the day......reading up iv found it can do. One comment is the nitrate test involves a little solid disk that is ment to dissolve, I have found it doesn't realy do so making me wonder if the results of that test can be reliable, going to try breaking the disk up abit see what that does. Found instructions were clear though did need to look up more about safe limits and what to do if the results point to poor quality or dangerous to fish as info in pack limited and abit contradictory in places. Having saidbthat this is a water test kit not a book on keeping fish or an introduction into chemistry so I would say thatnit makes any mention of fish or what to do if the levels out is a bonus. The test tube holder is cardbord, the instructions are a little leaflet and the colour scale is on the back of the pack as noted in other reviews, I can't say I have a problem with this, other reviewers have said would be better if holder were plastic, guess so but that would make it more expencive would rather pay for the chemicals and you can buy test tube rakes if you want somthing more hardwearing, cardboard recycles and I haven't seen just the chemicals for sale so when these run out you would end up getting another pack with a new cardboard rack. Tests take a bit more time than strips, two require you to wait 10 mins befor reading resalts so allow 30-40 mins to do tests so not as quick and easy to do as strips but my research on net befor buying suggested this is more accurate also works out cheaper and I quite enjoy doing it, nostalgic memorys of proper lab experiments whalst studying.

I decided to buy this test kit because it had a lot of positive reviews and I'm glad I did. It's very easy to use. As I hate the cold I decanted some pond water into a jug and did all the tests indoors - you only need 5ml of water per test. The box the kit comes in has a section where you can insert the test tubes while you are waiting for the test to be completed, and I'm pleased it's cardboard as it is ecologically friendly. There are labels for all the test tubes and tops so that you don't get confused while doing the tests. Also as the test tubes are flat bottomed so even if the box becomes damaged, the test tubes will stay upright while you're doing the testing. The leaflet that comes with the test kit has printed grids so that you can put in all the results and the date, which is really useful. All in all it's a very user friendly product that I enjoyed using. It's good value for money as the contents are enough to enable multiple tests to be carried out. And unlike some kits, this kit tests the ammonia levels in the water which is important as too much ammonia is dangerous for your fish. The water in my pond was good and I didn't need to do anything to it, but in a few weeks time I will drop in a pond bomb as I found these were the best yet for adding friendly bacteria to your pond.

The product appears to complete a good job with straight forward set of test tubes and reagents for each test all of these clearly maked for both identity and where applicable, usage levels for each test. On use of the tests all appeared to provide a clear result which can then be compared with the comparison charts on the rear of the outer packaging, however my results cannot be compared with a comparable benchmark for accuracy so they have to be accepted as being correct. On the downside the test tubes together with the reagents are packed in the packaging with use use of flimsy cardboard packaging which even after first use is showing signs of damage. As there are six tests (test tubes) together with a number of chemical bottles for the sake of a few pence it would be significantly beneficial for both testing and storage of the equipment and chemicals if a bespoke rack (say plastic) was included in the set. I am sure that most purchasers would welcome this large improvement at the cost of a few pence more on this twenty odd pound testing kit. Hence the four star rating.

use this make test kits all the time a must for anyone that has a pond

It works. It's easy to perform the tests and the colour changes are easy to see.

Who knew testing pond water could make me feel like a mad scientist? With this NT Labs Pond Lab Multi-Test Kit, I went from “casual pond owner” to “breaking bad, but with koi fish” in no time. First off, this kit has everything. Ammonia? Nitrite? pH? It’s like the Avengers of water testing, and I’m Captain Test-It-All. I had no idea what half these parameters even were before, but now I’m basically qualified to teach a college course in aquatic chemistry. The instructions are straightforward, but I still managed to feel like a genius performing these tests. Carefully dropping solutions into the tubes while squinting at color charts gave me a new appreciation for what lab scientists go through (except I was wearing sweatpants and holding a coffee mug that says "World's Okayest Pond Owner"). The results were accurate and super helpful. Apparently, my pond was on the verge of becoming a toxic wasteland—sorry, fish! But thanks to this kit, I was able to make the necessary adjustments and prevent a full-blown pond apocalypse. My fish now swim around like they’ve just upgraded to a 5-star resort. I also appreciate how many tests you get. 200 tests?! That’s 199 more times I get to pretend I’m a genius. Honestly, I might start offering pond-testing services to neighbors just for the thrill of it. In conclusion, if you own a pond and want to feel like a combination of a marine biologist, chemist, and superhero all at once, this kit is for you. Your fish will thank you, and you’ll have way too much fun.
