CaribSea Purple-Up 16oz

Purple-Up is a new pink and purple coralline algae accelerator. Since Purple-Up is not a fertilizer, itdoes not promote the growth of nuisance algae. How does it work? Purple-Up uses a unique dualmethod approach to coralline algae acceleration. It contains ionic calcium which immediately raisesdissolved calcium levels in your aquarium water. At the same time Super Sea Calcium (a 10 micronaragonite powder derived from natural seawater) targets the live rock surface. Super Sea Calciumdissolves in situ; delivering calcium, strontium, magnesium, and carbonate right where its needed.Purple-Up also replenishes iodine; an essential element for coralline algae tissues that quicklybecomes depleted in closed systems. Purple-Up is an excellent addition to any aquarium with stonycorals too! One bottle of Purple-Up replaces the typical multi product recipe for successful corallinealgae growth favored by advanced aquarists.
