Product: Blu Bios Test GH
In countries of origin of most of the ornamental fish, the land is poor in minerals.
In many countries of the world is exactly the opposite.
The rain dissolves the calcium and magnesium from the soil so that crosses and is enriched with mineral salts that constitute the total hardness.
With the GH test we can determine quickly and accurately the total hardness.
A comparison with the conditions in nature helps to combine the fish in the community aquarium the right way or at the time of playback.
A too high total hardness is lowered by mixing tap water with reverse osmosis water.
Instructions for use:
Shake well before using the reagent!
1. Rinse the tube several times with the water to be tested and then fill it up to the 5 ml mark. Dried, then, the tube externally.
