Particulate phosphate vs. phosphate solution

Phosphate supply in particulate form is much safer and more selective than in dissolved form. The phosphate is virtually " wrapped" in particles and can thus be ingested by polyps. With the help of symbiotic bacteria, these particles are finally broken down (" unwrapped") and the phosphate is provided directly to the coral. Studies have shown that the particulate phosphate supply is significantly more effective in terms of coral growth than the dissolved variant. Furthermore, a particulate diet also has a positive effect on the polyp extension, as these are requested according to their function (particle capture).

On the other hand, you can have very high dispersion losses when supplying dissolved phosphate - especially if the aquarium is initially only lightly stocked with corals. Dissolved inorganic phosphate can, for example, be taken up directly by algae or precipitate on rocks as well as substrate. Possible consequences are increased algae growth and the formation of phosphate deposits.

Recommendation for use Phos-Feed

Phos-Feed can be applied at any time of the day or night. Since the application causes the water to become somewhat cloudy and in order to take advantage of the corals' nocturnal polyp opening, Phos-Feed should preferably be dosed around the time the lighting is switched off. Temporary cloudiness of the aquarium water is normal.

Start with a daily dosage of 1 ml (small measuring spoon) Phos-Feed per 200 l aquarium water. Fill a container halfway with approx. 200 ml of reverse osmosis water and add the Phos-Feed. Mix powder and water well by stirring. Pour the suspension into the flow of the aquarium and rinse the container with aquarium water. If after four weeks phosphate concentration between 0.05 mg/l and 0.15 mg/l has not been reached in the aquarium, double the dosage to 2 ml (large measuring spoon) per 200 l. The maximum dosage of 4 ml per 200 l should not be exceeded.

Suspended Phos-Feed can also be added via a dosing pump. In this case, place the dosing tank on a magnetic stirrer so that the Phos-Feed does not settle.
