Caribsea - Purple Up - 16oz Bottle

Purple-Up™ is a new pink and purple coralline algae accelerator.

Since Purple-Up™ is not a fertilizer, it does not promote the growth of nuisance algae.

How does it work? 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.

At the same time Super Sea Calcium™ (a 10 micron aragonite powder derived from natural seawater) targets the live rock surface.

Super Sea Calcium™ dissolves in situ; delivering 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 too! One bottle of Purple-Up™ replaces the typical multi product recipe for successful coralline algae growth favored by advanced aquarists.
