Tropic Marin Phos-Feed is the first product to contain insoluble particulate phosphate minerals in combination with selected trace elements. The product works effectively directly on and in the coral. Tropic Marin Phos-Feed adds phosphate microparticles to the reef aquarium, which are filtered out of the water directly by the corals. Just like in the natural coral reef, this method avoids a lasting increase of dissolved phosphate in the water column. In this way, the corals are supplied directly with vital phosphate, and as much as is possible, phosphate adsorption by the rock and substrate is avoided. Particulate phosphate is particularly necessary in biological processes important for good and regular coral growth, beautiful polyp extension and bright coral colors.Tropic Marin Phos-Feed+ 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 e
