Coralline Purple•CX is specifically designed to encourage and accelerate growth of purple and pink coralline algae without fertilizing green algae. Because it is made from expensive marine aragonite, with added supporting minerals, it will not pollute your system like inexpensive aquatic muds of terrestrial origin may. It is phosphate and nitrate free.
250ml bottle Add 1 capful (5 ml) per 25 US-gallons (100 L) of marine aquarium water 3 to 4 times per week. Coralline Purple•CX will raise the calcium level in your aquarium. For best results, measure the calcium concentration and add as required to maintain the concentration between 410 and 450 mg/L (ppm).
