Review: Cost is high
Review: 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

## Features

- Calcium is one of the most important elements in a reef aquarium. Reef invertebrates, such as corals, crustaceans, mollusks, and even some type of encrusting algae, need calcium to grow and remain healthy. Over time, the calcium level drops as it is used by invertebrates, or as it reacts with excess phosphate. The API CALCIUM TEST KIT measures calcium levels as low as 20 mg/L to help you keep your reef inhabitants healthy.
- Contains 2 test bottles, easy-to-ready instructions, and glass test tube
- Do I need to test calcium parameters in a freshwater aquarium? No, calcium levels need to be monitored and maintained in reef or marine aquariums, as improper levels can be harmful to corals and crustaceans.
- For best results, test calcium levels with API CALCIUM TEST KIT in your saltwater tank weekly.

Calcium Testing kit instructions call for checking the water changing from pink to purple to blue.......my tanks all went pink to blue, but the only reference photo they give is a single purple square that never matched my colors.......the master test kit it awesome, but I'd pass on the calcium test, which were both the same price
