Our Granular Activated Carbon based on bituminous coal provides the best combination of pore size, particle size, high surface area, low ash, and hardness for chemically filtering aquarium water. In addition, test results indicate no leaching of phosphate. The high hardness level of this carbon prevents the dispersion of particles throughout the aquarium, which is more likely to occur with softer grades of carbon. Our Granular Activated Carbon meets American Water Works Association and Food Chemical Codex requirements.
"Pound for pound and hands down the best acropora that I've came across in the entire country - the corals are incredibly healthy and fully colored, and most importantly of all grown with the love and care of a true hobbyist. Would 110% go with 5th Alarm 7 out of 7 days of any week in any given year"

Visited 5AC today and the corals and frags are amazing. Look exactly like the pictures. These are how they look in after a dip and 5 minutes in my tank.
