OtherTropic Marin
Tropic Marin Phos-Feed is a targeted coral nutrient supply inspired by natural biological principles; phosphate is dosed in a targeted manner as insoluble particulates — the most effective way to deliver this essential nutrient — without continuously increasing the phosphate concentration of the water column. Stimulates coral growth and natural skeletal development with bright colors; includes trace elements like iodide, fluoride, and bromide. Start with 1 mL per 50 US gallons daily (mix in 200 mL RO water, pour into high-flow area, ideally when lights are off); double to 2 mL after four weeks if phosphate 0.05-0.15 ppm is not reached; max 4 mL per 50 US gallons.
