Product Reviews

  • Approximate dimensions: Outside bottom: 14-7/8" diameter x 2-1/4" High
  • Seal / O-ring is no longer included by Tetra. They state that it is not needed if the flow rates are followed and the filter is located properly above the water then the water should never fill up enough within the filter to warrant the need for the o-ring.
