PurpleUp – uses a unique dual method approach to coralline algae acceleration. This apporoach 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 its 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.
