E.S.V. Our 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.

The new carbon has a smaller particle size of 8 x 30 mesh (new) vs 4 x 8 mesh (old). This gives a higher surface area, resulting in faster and more efficient absorption of organics. If using a media bag, we recommend a 300 to 500 micron ( 50 - 35 mesh) bag. The carbon meets American Water Works Association and Food Chemical Codex requirements.

Specifications:
  • Molasses Number: 225
  • Iodine Number: 1050
  • Hardness Number: 92
  • Usage: 1/2 cup per 40 gallons (1 cup per 40 gallons for tanks without protein skimmers) replace monthly.
  • Weight: 3.5 lbs

Every month I replace 1 liter of activated charcoal (for 180 gallon) and everyone notices how great my tank looks. Don't really notice the yellow until it's gone. Need to soak in RO water for about 30 minutes to clear the dust. Once a week I shake the bag and afterwards I notice how much clearer ...Read More

How do you really evaluate carbon? I can say that my water is crystal clear. The rinsing of the carbon seems to be no worse than other that i have tried. I use this carbon in a MR-1 reactor. I use ESV when they have a product for my need. I can say without a doubt that i have used 80% of their produ...Read More
