Why owners like it
Ionic calcium immediately raises dissolved calcium levels in your tank water, according to CaribSea.
Super Sea Calcium, a 10 micron aragonite powder derived from natural seawater, targets the live rock surface and dissolves there, delivering calcium, strontium, magnesium, and carbonate right where the brand says it’s needed.
It also replenishes iodine, an element CaribSea notes is essential for coralline algae tissues and quickly becomes depleted in closed systems.
CaribSea says PurpleUp is not a fertilizer and does not promote the growth of nuisance algae.
CaribSea describes the approach behind PurpleUp as a unique dual method for coralline algae acceleration, backed by a US patent the brand cites as No. 7,565,883.
