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.

Has a unique dual method approach to coralline algae acceleration:

• Ionic calcium - Immediately raises dissolved calcium levels in your aquarium water.
• Ten micron aragonite - targets the live rock surface, where it dissolves in situ (in place), delivering calcium, strontium, magnesium and carbonate right where it is needed.

Features:

• Iodine replenishment: Purple Up replenishes iodine, an essential element for coralline algae tissues that quickly becomes depleted in closed systems.
• Easy to use: One bottle of Purple Up replaces the typical multi-product recipe for successful coralline algae growth favored by advanced aquarists.
• Conatins super sea calcium, a natural calcium derived from pristine tropical oceans.

Treats up to 4730 gallons
