Coral Up and Coral Up B
CaribSea’s Coral Up and Coral Up B offer an innovative way to grow and maintain a healthy and vibrant reef tank. They feature the performance of the patented Purple Up recipe, but with a trace element composition that includes ionic strontium and magnesium, in addition to 10 micron solid phase aragonite crystals meta-stable at a pH of 8.2, all specifically geared to scleractinian skeletal growth. Coral Up B, used in a 2:1 ratio to Coral Up, provides the alkalinity and pH support. Why 2:1? Because Coral Up is so concentrated with calcium it requires twice the alkalinity to balance.
