ELOS AQUA TEST KIT- General Hardness GH
General Hardness is primarily the concentration of the Calcium (Ca++) and Magnesium (Mg++), the two most important metal cations with more than single positive charge.
If the amount of these salts is low, then the water is called soft.
When their amount is higher, the water is called hard.
Total hardness is normally given in German degrees (dHø), whereby 1 dHø is equal to 10 mg/Lt dissolved Calcium oxide. The concentration of these salts inside the water effect the biological functions of plants and fishes. The optimal value for the General Hardness depends on the species of fish and plants. Where many African and South East Asian species fluorish in relatively hard water, South American ones may neeed soft water. By the way, if a range of hardness of 3 to 16 dHø is accepted, a range of 4 to 10 dHø is considered to be ideal.$14.99

ELOS AQUA TEST KIT- Calcium
Calcium is the primary building block of corals, calms, calcareous algae and many other organism that we grow in our aquarium. Without adequate supplies of calcium these organism will not flourish and most eventually waste away and die.
The ideal value of Calcium in the aquarium is:
- for the seawater aquarium 450 mg/Lt
- for the planted freshwater aquarium 100 mg/Lt
Because of the importance of calcium, it is necessary to keep inside our marine aquariums, the proper Calcium Level, testing it with an accurate test kit.$27.99
