Does a great job of measuring calcium!
I initially purchased the API Freshwater Master Kit and used it for many years before moving into the saltwater side of the hobby. I then purchased the Saltwater Master Kit (which I found was no different than the Freshwater one, except for the results card) and have used it for over a year, testing my parameters when I see fit. Once you have an established aquarium, the need to check parameters is greatly reduced...thankfully. However, once I started adding corals to my tank, I began reading online about Alkalinity and Calcium and how critical they are for the growth and health of corals. At the time, I didn't think much of it and continued maintaining my tank as I did before. Throughout the first year of owning my tank I would encounter new situations, such as algae growth and corals being closed. The latter was a pretty big concern because I believed it meant my corals weren't "happy". I began searching for reasons why they might be closed up. I chose to purchase both the calcium and carbonate hardness (alkalinity) kits to test my water. I was surprised when my tank was right where it should be. In fact, EVERY time I have checked calcium and alkalinity levels they are fine. I would eventually find the real reasons why my corals were closed (one of which is that sometimes they just close for a day or two to "recharge") aside from a calcium and alkalinity imbalance. While these API products are great, I would recommend that unless you are keeping a huge tank full of corals, or are keeping a large amount of SPS corals, there's no real need to purchase the additional calcium and alkalinity tests. If you want to make sure all your parameters are perfect, they are good products, but for smaller tanks and hobbyists keeping softies and LPS corals along with doing regular water changes, save yourself some money and time on maintenance!

Parfait
J'utilisai le test TETRA qui est une vrai galère avec 2 produits et une poudre et surtout qui ne donne pas les bons résultats... J'avais remarqué ce test utilisé dans une animalerie mais non commercialisé par cette dernière... Enfin le produit simple et fiable que j'attendais! je vous le recommande vivement
