CaribSea Purple Up Coralline Algae Growth Accelerator 16oz
Purple-Up is a pink and purple coralline algae accelerator designed to promote the healthy growth of coralline algae without encouraging nuisance algae growth. Unlike traditional fertilizers, Purple-Up does not contain nutrients that fuel unwanted algae blooms.
It uses a dual-action method: first, it provides ionic calcium that quickly increases dissolved calcium levels in the aquarium water. Second, Super Sea Calcium — a 10 micron aragonite powder derived from natural seawater — dissolves directly on live rock surfaces, delivering calcium, strontium, magnesium, and carbonate where they are needed most.
Purple-Up also helps replenish iodine, an essential element for coralline algae tissue that can become depleted in closed aquarium systems.

Heather McDonald –
I’ve used Purple-Up for three months in my reef tank. The coralline algae on my live rock has grown noticeably, with vibrant purple and pink hues. No increase in nuisance algae. The product is easy to add and works well with my existing setup.
Oliver Stewart –
The color change in my coralline algae was visible within a week. I noticed better texture and coverage on the rock. It doesn’t seem to affect other algae types, which is a relief after trying other products.
Phil Abraham –
After adding Purple-Up, my tank’s coralline algae became more robust and colorful. The iodine replenishment seems to be effective, especially in a small, closed system with limited water exchange.
