Biological Waterfall Filter Comparison              
"For any biological filtration to work, there literally needs to be billions and billions of bacteria working to purify the water.  They prefer to anchor onto things, which is why  
surface area is so important.  More surface area means more bacteria, and more bacteria means better biological filtration."    From page 89 in Aquascape Designs' Pond Builders Bible

"All bio filters of any type can be classified according to their Specific Surface Area (SSA).  The higher the SSA, the more probable it will be more effective as a fish pond filter.  
SSA refers to how much surface area per unit volume of media is available for colonization by bacteria inside fish pond filters."
