Trace elements are natural minerals, which are necessary for the aquarium inhabitants for active biological processes and especially needed by corals and invertebrates for skeletal growth. Seawater only contains these elements in small quantities, which are consumed quickly and in a very short time due to coral growth and other processes. Therefore, a regular addition of these trace elements is necessary.


  • Anionic essential trace elements in liquid form
  • In combination with Tropic Marin K+ ELEMENTS, which contains the essential cationic trace elements, in only two additives you will achieve all your trace element needs in just two additives.
  • Contains trace elements in pure mineral form
  • Suitable for aquaria with soft corals, LPS, SPS and/or crustaceans
  • Promotes strong growth and natural colouring of corals.
  • Corals do not lose colour due to a lack of trace elements.
  • Easy to use: whether dosed manually or with dosing pumps.


  • Tropic Marin A-ELEMENTS contains bromine, fluorine, iodine, lithium, vanadium, molybdenum and selenium in pure mineral form.

Application and dosage

  • Add 1 ml Tropic Marin A-ELEMENTS per 100 litres of aquarium water daily. The trace element solution should not be fed directly to the animals. When the consumption of trace elements by the corals is increasing, the dosage can be doubled (maximum dosage).
  • In the case of calcium addition with Tropic Marin BIO-CALCIUM, the same quantity of trace elements as calcium should be added: 5 ml of trace elements to 5 ml of BIO-CALCIUM.
  • Suitable for both manual dosing and dosing pumps.

Other recommended products

For a complete supply of trace elements, the additional use of Tropic Marin K+ ELEMENTS (cationic essential trace elements) is recommended.
