It is "ruffly" twice as effective as the other two . About 1.9 times the typical granules.
The effectiveness isn't a number we just came up with : )
This products main purpose is for removing arsenic from drinking water for human consumption. It is highly regulated and tested for both quality and effectiveness. The products ability to remove phosphate is closely tied to amount of iron oxide it contains. The HC product is about twice as heavy/dense as the other two and therefor contains around twice as much iron oxide for the same volume.
all that said, it is about twice as expensive as well. The main benefit in my eyes is that it is much harder and less prone to attrition and the creation of fines (dust) in both transport around the world to your home and inside your reactor.
