APICalcium Test Kit Saltwater Aquarium Water 1-Count Kit, 69L (69L)

Cost is high

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

This is my go to test kit for calcium. It is easy to use and the color change is readily discernable. I cant comment on accuracy of the test, but I am able to generate consistent numbers. The reason that I rate this at 4 rather than 5 is because each test requires 10 drops of reagent 1. However, for each test if you have typical levels of calcium in your reef, one would use 20 drops (roughly) of reagent 2. This means that you will consume all of reagent 2 and only about half of reagent 1. All API would need to do is increase the volume of reagent bottle 2 (and charge a little more) to get more tests from the kit.

At first I didnt get the instructions but than after watching a tutorial video on youtube i got it it was so easy

My only complaint is instructions are hard to understand.
