Particulate phosphate for targeted coral nutrient supply
Phosphate is one of the nutrients with high consumption and often low availability in the reef aquarium as well as in the unpolluted natural coral reef. Phosphate is essential in numerous growth processes of the skeleton and tissue of the coral.
In the natural coral reef environment, insoluble, particulate excretions of fish and plankton supply corals with phosphate essential for metabolism and growth. These particles can be very easily filtered out of the water and utilized by the corals. Tropic Marin® has applied this knowledge in a novel product, Tropic Marin® Phos-Feed, for the ongoing phosphate nutrition in reef aquariums.
Tropic Marin® Phos-Feed is modeled after the natural phosphate supply mechanisms seen in the wild coral reef environment. Now, for the first time in your reef aquarium, phosphate is dosed in a targeted manner, without continuously increased phosphate concentration of the water column. As a result, coral growth is stimulated and the corals show natural patterns of skeletal development and bright colors, just like in the intact coral reef under natural conditions. Insoluble particulate phosphates are the most effective way to deliver this essential nutrient to the corals.
Targeted application, best dosage control and optimum effectiveness through the use of insoluble particulate ingredients. Inspired by the best natural biological principles.
Inspired by the best natural biological principles, utilizes an innovative new transport mechanism for phosphates into the coral.
Tropic Marin® Phos-Feed contains insoluble particulate phosphates to enhance numerous biological processes in the coral for stronger growth and more intense colors.
The included halogen trace elements like iodide, fluoride and bromide, replace elements consumed by increased growth rate of coralline algae and corals.
Recent studies show that insoluble, particulate phosphates are much more effective for coral growth and care than dissolved forms.
Tropic Marin® Phos-Feed and Tropic Marin® Phos-Start are the first products that supply phosphate, in particulate form, to the coral in a targeted and dosed manner.
Phosphate Mineral Powder, Trace Elements (iodide, fluoride and bromide), passive ingredient: Pro-Reef Sea Salt
Application & Dosage
Application: Tropic Marin® Phos-Feed can be added at any time of the day or night. Since the application clouds the water somewhat and to take advantage of the corals' nocturnal polyp opening, Tropic Marin® Phos-Feed should preferably be applied around the time the lights are turned off. The temporary turbidity that forms is normal. The water is particularly clear after the turbidity.
Half fill a container with approximately 200ml of reverse osmosis water and add the calculated amount of Tropic Marin® Phos-Feed. Mix powder and water well by stirring. Pour the suspension into the current of the aquarium and rinse the cup with aquarium water.
Dosage: Start with a daily dosage of 1 ml (small measuring spoon) Tropic Marin® Phos-Feed per 200 l (50 US-gal) aquarium water. If after four weeks a phosphate concentration between 0.05 ppm and 0.15 ppm is not reached in the aquarium, double the dosage to 2 ml (larger measuring spoon) per 200 l (50 US-gal). We recommend not to exceed a maximum dosage of 4 ml per 200 l (50 US-gal).
Other product recommendations
We recommend supporting Tropic Marin® K+ Elements and A- Elements for good coral growth and bright colors or Tropic Marin® All-For-Reef as a comprehensive mineral supply to be dosed regularly.
