Sera USA Test Box Freshwater Master Kit

I think this is the best test kit on the market because:1. The test-tubes are robust, wide-mouthed, and have quantity lines clearly marked: this makes them easy to fill, easy to measure the exact amount, and easy to clean.2. The wide-bottomed tubes sit on the colour chart in white spaces left in the colour strips and are read from above: this makes the colours more intense and much easier to judge than a tube held vertically beside a colour chart.3. For several of the tests, the colour changes are far more pronounced (i.e. easier to judge) than in many other test kits I have tried.4. The reagent bottles arrive completely sealed and, once thoroughly pierced by the plastic needles in the caps, they easily dispense drops of consistent size.5. The box is really handy for storage, and has cutouts to hold the test-tubes whilst up to 4 tests are conducted simultaneously.

Buen material

io sono molto soddisfatto, la qualità è al top, tutto ben fatto

Bonne malette qui contient la plupart des tests essentiels. Une réelle différence avec les tests bandelettes. Petit bémol sur le test pH qui aurait mérité plus de précision (échelle de 0,5). Livraison en avance, emballage soigné.

This is a high quality test kit from Germany, which tests pH, GH and KH (in °dH), NH4/NH3, NO2, NO3, PO4, and Fe (in ppm*), and Cl. Easy to read color comparison charts are provided for every test, with the exception of Cl (of which ANY color equals dead fish).Kudos to Amazon for correctly indicating there is NO test for Cu, although the "sera aqua-test" booklet includes this test as part of the "standard" test kit. The user needs to pay close attention to the instructions within the "sera aqua-test" booklet: 1) The instructions are printed in 6 point type and cover few pages; 2) Pay attention! The sample size varies; 3) The English instructions are only four pages long.The instructions contain little information beyond running the individual tests - For example, there is no information I've found on how to open the reagent bottle; however, there is a handy prick in the bottle's cap (see my additional pictures with the product).Since this is a 'universal' German product, the manual's instructions are repeated in eighteen (18) different languages. Again, not much useful information in the manual (e.g. support URLs, contacts, "Sera Online Backup"**, etc) beyond test execution. There is some superfluous information in the manual, such as instructions for running a Cu test (NOT included) and a color chart for C02 concentration (a test classified as a specialty test for separate purchase by the "sera aqua-test" booklet).In conclusion, I recommend this product as a much better and comprehensive test kit than its closet competitor, the API Freshwater Master Test Kit and its problematic NO3 reagent #2. The advantage of the API product being oriented to American clientele is a plus if you are state-side. *ppm is equivalent to mg/l (do the math! :-))**"Sera Online Backup" - Nothing found in the usual search engines regarding this service, other than the mention of this service from various retailers, including Amazon. I found the site in Germany. If interested, send me an email an I'll send you the URL.
