Purple-Up is a specialized supplement designed to accelerate the growth of coralline algae in saltwater reef aquariums. It employs a unique dual method approach, combining ionic calcium with Super Sea Calcium powder to immediately raise dissolved calcium levels and target live rock surfaces for optimal nutrient delivery. Additionally, Purple-Up replenishes essential iodine, which is quickly depleted in closed systems but crucial for the health of coralline algae tissues. This product is an excellent addition for aquariums housing stony corals, offering a simplified alternative to traditional multi-product regimens favored by advanced aquarists.
