Phosphate Sponge

Kent Marine Phosphate Sponge is a ceramic medium which will adsorb phosphates quickly (within hours) when placed directly in the water flow. Works in fresh and saltwater aquariums or ponds to bring about 1.0 ppm of phosphate or silicates down to less than .05 ppm in a 120 gallon tank for every dry quart of medium. For silicate to be removed, phosphates must first be removed. Beads are cracked to expose more surface area and increase efficiency! This product will not release soluble aluminum compounds into your aquarium, causing negative reactions from your inverts, as competing products may. Will also absorb moisture for use as an air dryer for ozone, and can be renewed over and over in moisture removal service!

Nitrate Sponge

Kent Marine Nitrate Sponge is a granular zeolitic medium which works by two methods. 1) It slowly directly adsorbs small amounts of ammonia that are released by fish and natural processes, and 2) it fosters anaerobic bacterial denitrification due to its physical porous structure. This denitrification slowly reduces nitrate levels in the aquarium. It works well in freshwater tanks or tap water to remove toxic ammonia directly! Nitrate Sponge prolongs the time allowed between water changes by keeping nitrates low!

Toxic Metal Sponge

A regenerable, bead shaped resin which safely removes heavy metals. Safe for use in all aquatic systems. Removes copper, lead, mercury and other heavy metals from marine and freshwater aquariums. Also works well to remove metals from tap water. Contains special form macroporous cation exchange resins. Regenerable over and over again. Light beads turn a slight blue or gray, indicating exhaustion and need for regeneration. Resin life is about 2 years of service.

Kent Reef Carbon

Removes organic pollutants, stains, and entrained toxic gases in marine and freshwater aquariums or ponds. Contains the finest pelletized activated bituminous coal based carbon. Pore size is in the 20 to 2,000 Angstrom range, ideally suited for removal of large organic molecules. Super activated with very high iodine and molasses numbers. Less than .2% ash making it suitable for sensitive species such as discus. Will not leach phosphates or promote undesirable algae growth, suited to sensitive reef systems! Engineered for water flow, will not clog easily like small granular or pelleted carbons. Out performs any carbon especially coconut shell!

Kent Organics Absorption Resin

Removes organic pollutants, stain, and entrained toxic gases to provide a pure environment in marine and freshwater aquariums • Contains special form macroporous organics adsorption resins • Reduces or eliminates carbon usage • Regenerable over and over again • DOES NOT REMOVE TRACE MINERALS FROM THE WATER AS COMPETING PRODUCTS AND CARBON DO! • White beads turn to a light yellow or brown, indicating exhaustion and need for regeneration • Resin life is about 2 years of service.
