Product details
Sea-Lab 28 2 lb Box is a saltwater aquarium additive designed to restore and maintain calcium, strontium, and trace elements to levels found in natural seawater. In practical use, it helps keep these dissolved elements from dropping as they are depleted in a functioning reef aquarium. The goal is consistent element replenishment without relying on a time-release approach—Sea-Lab 28 is intended to work automatically as elements are used up.
Features:
- Restores and maintains calcium, strontium, and trace elements at sea-like levels
- Formulated as Sea-Lab Formula #28 for ongoing supplementation
- Designed to dissolve to replace depleted elements rather than act as a slow-release product
- Intended to be reliable for continued use in marine aquariums (“always works” as stated by the supplier)
- Stated to be non-overdosing (“cannot be overdosed” as stated by the supplier)
