Pea soup green ponds are largely due to excess nutrients in the water. Switching over to a higher grade bio media in your waterfall pond filter is the most effective method to naturally strip out that nutrient to create clean, clear water for your pond.

 

SSA refers to how much 'specific surface area' per unit of volume a bio media has for colonization by bacteria inside pond filters

Bio Media Direct Comparison Matrix Bio Media 400 SAA Lava Rock 86 SSA 500 SSA / 86 SSA= 4.65 That's over 450% more surface area for beneficial bacteria to colonize that will consume the nutrient out of the water within the same space in your waterfall filter!! It is also a media that lend itself to back-flushing for improved efficiency!!
