Continuum Coralline Purple CX - 250ml

Coralline Purple.CX is a marine aquarium additive designed to encourage and accelerate the growth of purple and pink coralline algae without fertilizing green algae. It is made from marine aragonite with added supporting minerals, so it will not pollute your system the way cheaper aquatic muds of terrestrial origin can. It is phosphate and nitrate free.

Coralline algae adds beauty to a reef tank and takes up space where unwanted organisms might otherwise grow. Because coralline algae is alive, it has to be introduced by adding small pieces of live rock that already have it growing on them. It doesn't take much, and your local aquarium store may have several types on small chunks.

Some coralline algae grows with little or no lighting, while other types seem to enjoy strong reef lighting, so it is worth experimenting. Keep phosphates as low as possible to encourage growth. Continuum also recommends maintaining calcium between 410 and 450 mg/L (ppm) and alkalinity of 7 to 11 dKH.

Supplied in a 250ml size. Suited to reef keepers who want to boost purple and pink coralline coverage.
