The Dymax Anti-Ammonia Rock is a natural filter media that absorbs ammonium, nitrite and nitrate from freshwater aquarium and pond water.

Key Features

  • Dymax states 500 g treats 200 litres
  • Helps maintain pH and reduces unpleasant odours
  • For freshwater aquariums and ponds
  • Place in a filter media bag in the filter flow

Good To Know

  • Absorbent media fills up over time and then stops working — replace it rather than relying on it indefinitely.
  • It is not a substitute for cycling: a working biological filter is what keeps ammonia at zero.
  • Keep testing ammonia and nitrite, especially in new or heavily stocked tanks.
  • Filter media supports good maintenance but never replaces regular partial water changes.
