Mitsuru Aquarium Ca/Mg Test – water test kit (drops)

This Yokuchi Mitsuru Aquarium Test Ca/Mg is a drop test kit for checking calcium and magnesium levels in aquarium water. It is aimed at hobbyists who run planted tanks or keep fish on RO water and need to know how their mineral balance is shifting over time.

Why it matters

• Two key elements: the kit targets calcium and magnesium only, the two minerals that most directly affect water stability in the tank.
• Plant growth: the manufacturer links these elements to correct plant development, so the test is useful where plant health is a priority.
• Complete set: the kit includes the reagents and the accessories needed for measuring, such as containers, syringes, test tubes, measuring spoons, comparison scales and instructions. The exact contents depend on the test type.
• Hardness and proportions: the test supports deliberate management of water hardness and the ratio of mineral components, which matters when water is prepared from RO water.

What it works with

The test fits planted aquariums and tanks run on RO water, where calcium and magnesium levels are often adjusted on purpose. It is part of the water chemistry category, so it is best used alongside other tests from the same range when monitoring the whole water profile.
