Filter Media: Chemical Filtration
We carry a number of chemical filtration products on this page. Chemical filtration is the removal of dissolved substances from the water.

Activated Carbon
Chemical filtration is most commonly accomplished by means of activated carbon. The carbon's micro-porous structure absorbs dissolved organics, chloramines, fish odors, toxic metals, toxic gases and growth inhibiting enzymes. We carry the Inland Seas, Kent Marine and ESV activated carbon.

Phosphate & Nitrate Removers
Besides activated carbon, a wide variety of resins, minerals, and other media have been employed by aquarists in an effort to remove either specific ions like phosphate or a wide range of largely unidentified substances from aquarium water. As you might guess, the Kent Marine Nitrate Sponge removes nitrate, and the Kent Marine Phosphate Sponge removes phosphate. Two Little Fishies PhosBan can be used by itself to remove phosphate, or it can be used in the Two Little Fishies PhosBan Reactor.

Media Bags
Boyds Chemi-Pure comes pre-bagged inside the jar. All other products need to be bagged using one of the Emperor or South Ocean Five media bags at the end of this section. All bags have ties sewn into the top for easy closure.

Poly-Bio-Marine Poly Filters
The Poly-Bio-Marine Poly Filters are pads that absorb and adsorb contaminants and other toxic materials that are found in nature or added to fresh and salt water with or without fish and invertebrates. Medication added to aquariums for treatment of diseased fish will automatically be removed by the Poly Filter (after serving their intended purpose). The pads are placed in any filter in a place where chemical filtration media is intended (generally, after the larger sediment has been filtered out).

Brightwell Aquatics PhosphatR Regenerable Phosphate Resin, 500 ml
Brightwell Aquatics PhosphatR Regenerable Phosphate Resin, 500 ml
Usually Ships in 1 to 2 Business Days
Our Price: $38.57 In Stock!

  • Next-generation regenerable phosphate adsorption resin
    effective in marine aquaria; will also remove silicates
  • Far more effective than activated alumina and granular ferric
    products
  • Will not negatively impact water quality nor release phosphate
    or silicate once exhausted; will not break up or disintegrate like ferric medias, and contains no aluminum to dissolve in aquaria and harm inhabitants
  • Synthetic polymer resin beads provide for durability and excellent flow characteristics; may be employed in fluidized-bed, canister, or passive filtration
  • Regenerable up to five times, dramatically increasing cost
    effectiveness
  • Basic Instructions: Prior to first use, rinse resin under a stream of purified water. For initial application on aquarium, use 1 ml of PhosphatR per 1 US-gallon of water in system and monitor phosphate concentration during usage. Subsequent application of resin may be at the rate of 2 ml per 1 US-gallon.

Inland Seas Marine & Reef Activated Carbon is a premium activated carbon. Activated carbon is a bituminous coal based pelletized carbon. Carbon is used to purify aquarium water by removing dissolved organics, medications, and yellowing compounds. This carbon has a wide range of micro pores and macro pores for superior removal of both small and large compounds. Pelletized carbon allows optimum water flow in and around the carbon, and resists trapping of fine particles. Inland Seas Marine & Reef Activated Carbon has a high hardness value to reduce dust.

To use, place carbon in a polyester or nylon filter bag, such as the Emperor Aquatics Media Bag 4" X 8" (Coarse, 800 Micron). Place the bag in the sump, tank or in a canister or power filter. Use approx. 1/2 lb per 50 gallons of tank volume (or more if there is a heavy bio-load). Replace carbon every 2 to 4 months.

Our Price: $9.50 In Stock!

1 liter, .26 gallons

The E.S.V. Granular Activated Carbon, based on bituminous coal, provides the best combination of pore size, large particle size, high surface area, low ash, and hardness for chemically filtering aquarium water. In addition, test results indicate no leaching of phosphates. The high hardness level of this carbon prevents the dispersion of particles throughout the aquarium which can occur with softer grades of carbon. The large particle size facilitates water movement through the carbon and helps prevent the removal of planktonic food organisms via mechanical filtration.
