GH+ Mag

Increase GH value in freshwater aquariums
Recommended for aquariums using Seiryu, Mountain, or similar rocks
GH+ Mag is a special supplement that increases only the GH component provided by magnesium. It is essential when using decorative rocks such as Seiryu,
Mountain, or similar types capable of releasing calcium.
It does not contain chlorides, so it does not negatively affect conductivity or plant growth.
It is the safest method to add salts to aquarium water without introducing harmful pollutants, as can occur when using tap water.
For proper dosing, it is recommended to periodically test the water with
Oceanlife Aquatic Lab GH.

When using calcareous rocks in aquarium setups, a certain amount of calcium will be released into the water, raising the GH. By using the software on our website, you can easily rebalance the Calcium:Magnesium ratio, bringing GH to the desired level regardless of the starting value.
5 ml per 20 liters of osmosis water increase the GH value by 1.25 points and the magnesium value by 5.38 mg/L.
5ml in 20L = +1.25 dGH
+5.38 mg/L Mg
