Hagen Fluval Lab Series Phosphate Remover

Fluval Lab Series Phosphate Remover rapidly adsorbs large quantities of phosphate, silicate and dissolved organics without leaching adsorbed substances. 150g removes up to 20 mg/L (ppm) of phosphate per 50 US gal. (189 L). Maintaining low levels of phosphate will result in cleaner, healthier aquarium water while allowing corals to efficiently absorb the calcium they require to grow and reproduce. Phosphate Remover contains Ferric Oxide, an iron-based phosphate binder ideal for use in aquarium filters. Will not affect pH or Hardness. For use in freshwater and marine environments.
