ZOOTONIC - Concentrated liquid zooplankton substitute

Product description

Tropic Marin® ZOOTONIC is a high-quality plankton substitute to supply plankton filter feeders in saltwater aquariums with all the vital nutrients such as amino acids, highly unsaturated fatty acids and vitamins.

In a gentle process, the nutrients for the filter feeders are digested without heating, ensuring that all vitamins and nutrients are preserved. ZOOTONIC is suitable as complete diet.


  • Highly concentrated complete feed for plankton filter feeders.
  • The lobster eggs included provide the animals with high-quality amino acids, highly unsaturated fatty acids and vitamins.
  • Suitable for soft corals, LPS, SPS and other filter feeders.
  • Easy-to-dose liquid solution.





Tropic Marin® ZOOTONIC contains crustaceans and glycerol.

Application and dosage

Using the 50 ml bottle:
Shake the bottle well before use. Attach the enclosed tube to the syringe and measure the desired amount of ZOOTONIC with the syringe. The air that gets into the tube and syringe while pulling the syringe, does not affect the dosage. The bottom edge of the plunger always displays the correct dosing amount even if the desired quantity of ZOOTONIC, due to the air drawn in, is only in the tube and not in the syringe chamber. The air drawn in serves to empty the tube during dosing.

Using the 200 ml bottle:
Shake the bottle well before use. Turn the pump head counterclockwise until it pops out. Pressing the pump head once is equivalent to 1 ml.

Begin with a daily dose of 0.1 ml per 100 l (26 US-gal) of aquarium system volume and increase the dose when necessary.

For the best possible distribution in the aquarium, Tropic Marin® ZOOTONIC should be dosed several times a day into the flow of the pump.

Maximum dose:
A daily dose of 0.5 ml per 100 l (26 US-gal) of aquarium system volume should not be exceeded. When dosing ZOOTONIC, the dosage of other products that (also) incorporate organic carbon should be reduced accordingly due to their resulting increase in oxygen consumption.

Store the bottle tightly sealed, in a cool and dark place!
Refrigerate after opening to prolongs shelf life.
