Components Strong contains concentrated trace elements intended for use in reef aquariums.
Components Strong in combination with Calcium, Magnesium, KH Buffer and Reef Mineral Salt are a complete set designed to maintain a reef aquarium by the method proposed by H. W. Balling, therefore these products should be used in parallel.
Due to the fact that the microelements in the aquarium are consumed in the right proportion with the macroelements, the concentrations of Components Strong have been developed based on other values.
Only the use of the entire range of Aquaforest products ensures effectiveness and guarantees the chemical balance in the aquarium.
The amount of microelements fed depends on the individual needs of the aquarium for magnesium and calcium.
Components Strong come as a set and they can’t be bought separately. 
Set:
Component A Strong
Component contains concentrated strontium and barium. 
The amount of strontium and barium depends on requirements for magnesium and calcium.

Recommended use with Aquaforest Calcium powder. 
Capacity: bottle of 75ml
Component B Strong
Component contains concentrated heavy metals. 
The amount of heavy metals depends on requirements for magnesium and calcium. 
5 ml should be added to 1 litre of ready solution of calcium chloride.
Recommended use with Aquaforest Calcium powder. 
Capacity: bottle of 75ml
Component C Strong
Component contains concentrated iodide and fluoride. 
The amount of iodide and fluoride depends on requirements for calcium. 
5 ml should be added to 1 litre of ready solution of sodium bicarbonate. 
Recommended use with Aquaforest® KH Buffer powder. 
Capacity: bottle of 75ml
Component K Strong
Component contains concentrated potassium. 
The amount of potassium depends on requirements for magnesium and calcium. 
5 ml should be added to 1 litre of ready solution of magnesium chloride and mineral salt.
Recommended use with Aquaforest® Magnesium powder and Reef Mineral Salt.
 Capacity: bottle of 75ml.
