In this video, we'll explain what Purple Up is and how it works.

CaribSea Purple Up is a pink and purple coralline algae accelerator. Since Purple Up is not a fertilizer, it does not promote the growth of nuisance algae. Purple Up uses a unique dual method approach to coralline algae acceleration. It contains ionic calcium which immediately raises dissolved calcium levels in your aquarium water while simultaneously targeting the surface of live rock.

This liquid supplement, available in 3 sizes, delivers calcium, strontium, magnesium, and carbonate right where it's needed. Purple Up also replenishes iodine, an essential element for coralline algae tissues that quickly becomes depleted in closed systems.

Purple Up is an excellent addition to any aquarium with stony corals. One bottle of Purple Up replaces the typical multi-product recipe for successful coralline algae growth favored by advanced aquarists.
