Tropic Marin® Phos-Feed is a ground-breaking particulate phosphate supplement engineered to deliver targeted, biologically appropriate phosphorus directly to corals. In ultra-low nutrient reef systems, traditional liquid phosphate dosing can lead to rapid shifts in water chemistry, sparking nuisance algae outbreaks. Phos-Feed bypasses this issue by supplying phosphate in insoluble, particulate mineral form. These microscopic particles are captured directly by corals, mimicking their natural consumption of plankton. Fortified with essential halogen trace elements like iodide, fluoride, and bromide, Phos-Feed supports the accelerated metabolic growth rates of stony corals and beneficial coralline algae without spoiling water clarity.
Key benefits
Targeted Particulate Delivery: Microscopic particulate phosphates are captured directly by coral polyps, mimicking natural feeding in the wild.
Safe for Low-Nutrient Tanks: Prevents the sudden liquid phosphate spikes that stress corals and spark nuisance algae.
Enriched with Halogens: Includes iodide, fluoride, and bromide to replenish trace elements rapidly consumed by thriving corals.
Accelerates Coral Calcification: Promotes dense skeleton building, stronger tissue growth, and more vibrant coloration in SPS and LPS.
No Water Clouding: Specialized mineral particles dissolve slow-release style, leaving your display tank sparkling clean.
Specifications
Net weight: 300 g (10.58 oz)
Form: Fine particulate mineral powder
Primary purpose: Targeted phosphate supplementation for coral growth and coloration
Water type: Saltwater (Reef systems)
Intended users: Reef keepers, ultra-low nutrient system (ULNS) aquarists, and coral breeders
Suggested use
Initial Dosing: Add 1 level measuring spoon (included) of Phos-Feed per 50 US gallons (200 L) of aquarium water 2 to 3 times a week.
Preparation: Mix the powder with a cup of aquarium water, stir vigorously to suspend the particles, and pour directly into a high-flow area of the tank.
Monitoring: Regularly test phosphate levels. If phosphate continues to fall, slowly increase dosage until a stable background level of 0.03–0.08 ppm is achieved.
Ingredients Phosphate Mineral Powder, Halogen Trace Elements (iodide, fluoride, bromide), Pro-Reef Sea Salt.
Guaranteed Analysis
Contains essential particulate phosphate compounds and targeted halogen trace minerals.
Storage and safety
Store in a cool, dry place. Keep the jar tightly sealed to prevent moisture exposure.
Keep out of reach of children and household pets.
Warnings
For aquarium use only. Not for human consumption.
Do not overdose. Test phosphate parameters regularly to avoid elevated nutrient levels.
What’s included
1 x Jar of Tropic Marin Phos-Feed (300 g / 10.58 oz)
1 x Measuring scoop
Why choose Tropic Marin Phos-Feed is the most biologically advanced way to handle pale, starved corals in clean reef tanks. By targeting corals directly through particle capture instead of elevating dissolved phosphates in the open water, Phos-Feed guarantees safe nutrient uptake, incredible tissue colors, and stellar coral growth without feed-limiting algae blooms.
