Media Reactors

An aquarium media reactor increases filtration performance and handles specialized media that a standard aquarium filter isn’t designed for. A fluidised media reactor pushes water up from beneath the media to increase contact time.

A GFO reactor, or Phosban reactor, gently tumbles GFO (granular ferric oxide) to remove phosphate, which helps algae control and coral health.

A carbon reactor is a fluidized media reactor that tumbles carbon or other media to clarify and clean water.

A biopellet reactor uses special biopellet media to house and feed bacteria, which then consume excess nutrients and waste before being skimmer out or consumed by coral. A biopellet reactor is an organic carbon dosing system to create an ultra low nutrient aquarium system.

A biodenitrator is a Sulphur media reactor that removes nitrates through anaerobic biological filtration.
