Phos-Start & Phos-Feed

Particulate phosphate supply for your aquarium

Bild Aktuelles - Phos-Start + Phos-Feed.png

Tropic Marin Phos-Start & Phos-Feed are based on the mechanisms of nutrient supply as they occur in the natural environment of coral reefs. Insoluble, particulate excretions from fish or plankton provide the corals with phosphate and all other necessary substances that are responsible for intact microbiology, vigorous coral growth and beautiful colors. Tropic Marin has implemented this knowledge in a new product for the commissioning of reef aquariums.

Tropic Marin Phos-Start can be used for setting up all types of saltwater aquariums, but is particularly suitable for setting up reef aquariums with dead rock or reef ceramics and for reef aquariums without a substrate. Such aquariums have a low supply of organic bacterial food and nutrients to stimulate bacterial and coralline algae growth.

Tropic Marin Phos-Feed can be used for the ongoing phosphate supply in reef aquariums.

New bottles for liquid products

Bild Aktuelles - Flaschen.png

We are happy to present our new Tropic Marin® bottles. These are round, have a logo relief on the top and have a number of advantages:

  • The new bottles require less plastic than the previous model and are completely recyclable.

  • Precise dosing: With a dosing insert on the cap, the required amount can be easily measured in the dosing cup that is included.

  • Better availability: In order to avoid delivery bottlenecks and to ensure continuous production, Tropic Marin® is now having its own bottle model made.

  • Faster production: With the new round bottle, we can speed up production and thus prevent delivery bottlenecks.



The bottling of the liquid products is gradually being switched over to the new bottles. The first varieties will be available in stores shortly.

Our four types of salt are now available in practical boxes. The 12.5 kg carton has a handle for easy carrying, the 20 kg carton has handle holes on the sides.

By using cardboard packaging, we can save a large amount of plastic. The salt is still packed to protect it from the weather. (Of course our buckets are still available.)

Increase in production capacities

Bild Aktuelles - TM Logo.png

In order to be able to supply our customers worldwide faster by sea, Tropic Marin has decided to set up a production site in Turkey. The German-Turkish team produces under the direction of Tropic Marin with the same pure raw materials and under the same quality requirements as in Germany. In just eight months, Tropic Marin established a production company and quality assurance laboratory in Turkey. Each batch is checked by ICP-OES in the Tropic Marin laboratory.


The first 20 containers of Tropic Marin salt were shipped at the beginning of the year and are already in numerous aquariums. We are very pleased to have expanded our production capacity with our Turkish partners and to the highest production standard.
