Essential Cationic Trace Element Supplement for Reef Aquariums

Dose with Pro-Coral A- Trace 2 For the best results!


Three Sizes Available:

  • 200 mL
  • 500 mL
  • 1000 mL


In the ocean, there are tiny amounts of essential trace elements such as iodine, lithium, manganese, etc. that can be depleted rapidly in household aquariums as corals and invertebrates grow. Tropic Marin Pro-Coral K+ and Pro-Coral A- are formulated to replenish those elements in an easy to dose balanced, liquid additive. When trace element levels start to get low corals can lose their color and stop growing completely.

  • Doser Ready
  • Easy to use
  • No mixing required to use
  • Contains required cationic trace elements
  • Supports natural coral color and growth



For a complete trace elements supply, we recommend the use of both trace element solutions, Pro-Coral A- and Pro-Coral K+.

Add 1 ml trace elements of each solution per 100 l / 25 US-Gal. of aquarium system water volume daily. The trace elements solution must not get directly onto the animals. The demand for trace elements increases with increased aquarium population density. In heavily populated aquariums, dosage may be increased up to the maximum dosage below.


Maximum dosage: Do not exceed a dosage of 2 ml per 100 l / 25 gallons of aquarium system water volume per day.
