CaribSea Purple Up Coralline Algae Accelerator

Carib Sea

PurpleUp™ uses a unique dual method approach to coralline algae acceleration. This approach is so unique that PurpleUp™ has been awarded a US patent (US patent No. 7,565,883). It contains ionic calcium, which immediately raises dissolved calcium levels in your aquarium water. At the same time Super Sea Calcium™ (a 10 micron aragonite powder derived from natural seawater) targets the live rock surface. This dissolves in situ, delivering calcium, strontium, magnesium, and carbonate right where it’s needed. PurpleUp™ also replenishes iodine, an essential element for coralline algae tissues that quickly becomes depleted in closed systems. PurpleUp™ is not a fertilizer, it does not promote the growth of nuisance algae.
