ZERO PHOS Resin - RAPID Phosphate Removal

  • ZERO PHOS Resin is a premium phosphate adsorption resin for freshwater, marine and reef aquariums that removes unwanted phosphate (PO4) and silicate (Si).
  • ZERO PHOS Resin will give you better results than GFO (Granular Ferric Oxide) or Alumina based products.
  • ZERO PHOS Resin will significantly improve water quality by removing unwanted phosphate and silicate, and it will not release phosphate or silicate back into the aquarium once it reaches capacity!
  • ZERO PHOS Resin will not break up or disintegrate like GFO, and does not contain aluminum that can dissolve in aquariums and harm fish, corals or invertebrates.
  • ZERO PHOS Resin is 100% REEF SAFE!
  • ZERO PHOS Resin is a synthetic polymer resin bead that is durable and may be employed in canister filter, a media reactor, or using a filter media bag.
  • ZERO PHOS Resin costs a fraction of comparable resins and phosphate media and will save you money!
  • ZERO PHOS Resin includes a FREE High Quality, Nylon Filter Media Bag!


General Directions:
Rinse ZERO PHOS Resin with purified water prior to using in aquarium.
Use 1 mL of ZERO PHOS Resin per 1 US gallon of water in aquarium.
Monitor phosphate levels during usage.
Additional ZERO PHOS Resin may be used at the rate of 2 mL per 1 US gallon if more phosphate reduction is needed.
When the phosphate level has not changed for a period of 4 - 6 hours, remove resin and reapply as needed.

Filter Specific Directions:
Media Reactor: Follow instructions of reactor manufacturer for optimal volume of filter media to use in reaction chamber.
Start at a low flow rate, then adjust flow rate to keep ZERO PHOS Resin in a steady tumble in the lower 2/3 of reactor chamber.
Flow rate should not be such that ZERO PHOS Resin is dispersed into the aquarium.
Leave ZERO PHOS Resin in place until phosphate reaches desired level or remains unchanged.

Canister Filter: Load ZERO PHOS Resin into included filter media bag and place in canister filter cartridge as directed by filter manufacturer.
Leave ZERO PHOS Resin in place until phosphate reaches desired level or remains unchanged.
Slower flow of water through the canister filter will result in maximum effectiveness of ZERO PHOS Resin.

Media Bag: Place ZERO PHOS Resin into included filter media bag and place in an area of aquarium with low to medium flow.
Turn the filter media bag over once during usage to shift the resin beads and increase the effectiveness.
Leave ZERO PHOS Resin in place until phosphate reaches desired level or remains unchanged.
