Eliminates reactive phosphate from all marine & reef aquariums.
Determine phosphate concentration in aquarium prior to first use by testing with an accurate test kit. Add product to aquarium near a mechanical filter or protein skimmer intake at the maximum rate of 5 ml (1 capful) per 20 US gallons daily for each 1 ppm of phosphate present in the system. When used in this fashion, 250 ml treats up to 1,000 US gallons (3,785 L). Add weekly at the same dosage to maintain an immeasurable reactive phosphate concentration.
Determine phosphate concentration in aquarium prior to first use by testing with an accurate test kit. Each ml of Brightwell Aquatics Phosphat-E will eliminate 1 ppm of reactive (available) phosphate in 4 US-gallons (15.142 L) of water. The result is an inert particulate that is permanently removed from the aquarium via mechanical filtration and protein skimming. To maximize the rate of phosphate removal, Phosphāt-E should be added to the aquarium near the intake of a mechanical filter or protein skimmer. Doing so will enable the inert particulate phosphate compound to be effectively removed from the aquarium. Particulate material not removed by filtration will remain inert and the bound phosphate non-reactive indefinitely under normal aquarium conditions. The maximum dosage should not exceed 1 ml per 4 US-gallons (15.142 L) daily, as too rapid a decrease in the concentration of phosphate may irritate sensitive corals, particularly if the phosphate concentration has existed at a relatively high level for an extended period of time (e.g. 3 - 6 weeks). The concentration of available phosphate in marine aquaria should not be allowed to exceed 0.05 ppm for any lengthy period of time; available phosphate in the presence of other substances can indirectly negatively impact the appearance of an otherwise beautiful marine aquarium. If corals or other invertebrates appear to react negatively to the addition of the product, it may be an indication that reactive phosphate is being removed too aggressively; decrease dosage by 50% and continue treatment until phosphate concentration appears to be immeasurable.
CAUTION: Harmful if swallowed. May cause eye or skin irritation. If in eyes, flush with water for 15 minutes, get medical attention. If on the skin, wash thoroughly with water. Keep out of reach of children. Not for human consumption.
