liquid zooplankton replacement 

Product description

Tropic Marin® Zootonic is high quality plankton replacement for feeding plankton filter feeders in the seawater aquarium with all nutrients such as amino acids, highly unsaturated fatty acids and vitamins necessary for life.

The nutrients for the filter feeders are solubilised in a gentle process not involving heat so that all vitamins and vital substances are preserved. Tropic Marin® Zootonic is suitable for use as a complete feed.


  • Highly concentrated complete feed for plankton filter feeders
  • The small crustaceans contained in the feed supply the animals with high quality amino acids, highly unsaturated fatty acids and vitamins

  • Suitable for soft corals, LPS, SPS and other filter feeders

  • A liquid solution and therefore easy to add to the aquarium


crustaceans, glycerine

Application & Dosage

Using the 50 ml bottle: Shake the bottle well before use. Place the enclosed flexible tube on the syringe and use the syringe to measure the required amount of Tropic Marin® Zootonic. The air which enters the flexible tube and syringe when the syringe is loaded does not influence the amount to be added to the aquarium. The lower edge of the piston always shows the right quantity to be added even if the required volume of Tropic Marin® Zootonic is only in the flexible tube and not in the syringe chamber. The air which is drawn into the syringe helps empty the flexible tube during the addition of the feed to the tank.

Using the 200 ml bottle: Shake the bottle well before use. Turn the pump head to the left until it pops out. One press on the pump head corresponds to 1 ml.

Adding the feed to the aquarium: Start with daily doses of 0.1 ml for every 100 l of aquarium volume and increase the quantity as required. To obtain the best possible distribution in the aquarium Tropic Marin® Zootonic should be added to the flow from the pump (several times) each day .

Maximum dose: A daily dose of 0.5 ml per 100 l aquarium volume should not be exceeded. Because of the oxygen consumption the addition of products with organic charcoal should be correspondingly reduced.

Store the bottle firmly closed in a cool, dark place. Cooling prolongs its storage life.

Not suitable for human consumption.

Other product recommendations

For phytoplankton filter feeders we recommend Tropic Marin® Phytonic as a liquid phytoplankton replacement. Tropic Marin® Zooton – Powdered zooplankton substitute for hard corals and other zooplankton feeders. Tropic Marin® Phyton – Powdered phytoplankton substitute for soft corals, bivalves and other micro filter feeders.

To check the nutrient concentrations and for supplying living microplankton, we recommend the effective bio-reactor Tropic Marin® Bio-Actif-Reactor 5000 in conjunction with the Tropic Marin® NP-Bacto-Tricks as filter media or a fluidised bed sand filter (e.g. TMC BioReact 500), in conjunction with the Tropic Marin® NP-Bacto-Pellets.
