This refill replenishes the GH reagent for the Yokuchi Mitsuru drop test line. It is aimed at aquarists who check mineral content in their water regularly and want to react quickly when values change, especially in tanks where RO water is used for water changes.
Why it matters
- GH measures the mineral level in the water, which is one of the basic parameters affecting stability of the aquarium.
- The test is a precise drop method, so measurements can be repeated and compared over time.
- GH readings help assess stocking choices and water conditions in tanks where mineral content must be controlled.
- It is useful for keeping track of water quality after RO water is added, since RO water contains very few minerals by default.

What it works with

It fits setups that rely on RO water for water changes and need to monitor the minerals added back into the tank.

Frequently asked questions
GH measures the overall hardness of the water, which shows the level of minerals in it. Knowing this helps you assess the water's mineral content for your tank.
The test is especially useful in planted tanks, shrimp tanks, and aquariums where water from reverse osmosis (RO) filters is used for water changes. It is also suited to any setup where precise water parameter control matters.
RO water is very low in minerals, so the GH level after water changes can differ from what you expect. Measuring it lets you see the actual mineral content and adjust your water accordingly.
Each test set includes reagents and accessories such as measuring containers, syringes, test tubes, color scales, and instructions, depending on the test type. Check the product listing to confirm what this refill package contains.
GH and KH are both basic parameters for tank stability, but they measure different things: GH reflects minerals, while KH reflects the carbonate buffer that helps keep pH stable. The GH/KH test measures both values.
