CaribSea Purple Up 8oz
This product will speed up coralline growth in your aquarium
PurpleUp accelerates coralline algae growth in salt water aquariums. It uses a unique dual method approach to accelerate growth. 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..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.
