Concentrated strontium gluconate supplement (10,000 mg/L) for the reef tank that restores and maintains strontium at the level existing in natural seawater. It is especially needed in densely populated aquariums that require a continual supply of strontium.
It has a pH of 8.2 and is neither acidic nor alkaline.
The gluconate complex has several advantages: it increases the bioavailability of strontium, it provides a rich source of metabolic energy to maintain maximum coral growth, and it blocks the phenomenon of strontium precipitation and carbonate hardness depletion ( alkalinity).
Gluconate does not contain nitrogen or phosphorus and therefore it is biologically impossible for it to lead to algae growth in a properly maintained system.
Use 1 capful (5 ml) per 80 L (20 US gallons) twice a week.
