Coral Essentials Calcium + Trace

Product overview

Coral Essentials Calcium + Trace is made in Australia. It is a concentrated calcium supplement for marine reef tanks, with selected trace elements mixed in.

SPS and LPS corals pull calcium from the water to build skeleton. If calcium falls below natural seawater levels, growth can stall and tips can become brittle. This 135,000 ppm solution supplies available calcium plus Coral Power Trace A and B and other minor traces, so you can support calcium and those micros from one bottle.

Key features

• Concentrated calcium: 135,000 ppm liquid for high-demand tanks and ongoing calcification.
• Traces included: Blended with Coral Power Trace A and B and other minor traces, so you do not need extra bottles for those micros.
• Simpler routine: Traces are dosed in a set ratio with each calcium addition.
• Skeleton growth: Helps keep calcium in the range hard corals need for thicker growth.
• Dosing pumps: Suitable for automatic dosing reservoirs.

Water and system compatibility

• Water: Marine / saltwater reef aquariums only. Not for freshwater or planted tanks.
• Target: About 420–440 ppm calcium.
