AquaMaxx's protein skimmers and filter media are designed to improve aquarium water quality, and reduce and remove organic compounds from the water column. The skimmers 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, the company states. Each model includes a Sedra or Sicce skimmer pump upgraded with a special needlewheel impeller to shred incoming air bubbles into micro bubbles for better performance, and are rated for aquariums from 50 to 550 gal. Each filter media formula is designed and tested for use in saltwater aquarium systems, and BioMaxx Plus BioPellets initiate a more efficient denitrification process that removes nitrate and phosphate from aquarium water, the manufacturer says. Carbon One reduces and eliminates organic pollutants, odors and discolorations from aquarium water, and Phosphate Out is a granular ferric oxide adsorptive filter media that removes phosphate, the company adds.
