CaribSea's Purple Up Coralline Algae Accelerator encourages the growth of desirable pink and purple coralline algae and not nuisance algae.

Unique Dual Method Approach to Coralline Algae Acceleration

1) Ionic Calcium: Immediately raises dissolved calcium levels in the aquarium water.

2) 10 Micron Aragonite: Targets the live rock surface, where it dissolves in situ, delivering calcium, strontium, magnesium and carbonate right where it is needed.

Iodine Replenishment: Purple Up also replenishes iodine, an essential element for coralline algae tissues that becomes quickly depleted in closed systems.

Easy To Use: One bottle replaces the typical multi-product recipe for successful coralline algae growth favored by advanced aquarists.

Contains Super Sea Calcium: Natural calcium derived from pristine, tropical oceans.
