AquaMaxx AM-S Series Protein Skimmer

AquaMaxx in-sump protein skimmers are built using exceptional cell-cast acrylic, bubble plates and easily adjustable riser tubes. They are rated for aquariums up to 550 gallons yet are thin enough to be concealed in a sump underneath your aquarium.

AquaMaxx in-sump protein skimmers remove organic waste from aquarium water. They create a strong mix of small air bubbles and turbulent water movement to force protein, waste and other materials into a collection cup for easy removal.

AquaMaxx skimmers are computer-precision engineered and utilize the latest filtration technology to deliver the performance and value you are looking for in a protein skimmer.

AquaMaxx in-sump protein skimmers are easy to setup and maintain. Just twist the knob counter clockwise at the top of the riser pipe to adjust the foam level to wet or dry.

Maintenance is simple. A removable collection cup makes cleaning easy. Plus, every AquaMaxx protein skimmer includes a drain fitting for hobbyists who want to setup a separate reservoir for skimmate. A silencer located at the top of the riser tube eliminates noise from the venturi.

AquaMaxx protein skimmers were designed from the ground up with the hobbyist in mind. All AquaMaxx protein skimmers have rubber feet that isolate noise and reduce vibration.

AquaMaxx protein skimmers are computer designed. Each unit is precision-cut and made of polished cell-cast acrylic.

AquaMaxx in-sump protein skimmers feature Sedra or Sicce pumps with special needlewheel impellers to produce large amounts of air with optimum bubble size. These pump and protein skimmer combinations deliver unprecedented performance and reliability. Aquarium waste will be vigorously removed from your tank so you can focus less on maintenance and more on enjoying your piece of the reef.

Picked up this yesterday and no regrets! Easy set up, no break in period, picked up where my G4 left off, super quiet, well built. I would recommend Aquamaxx skimmers to anyone.
