The Dymax LS/SLS Skimmer violently mixes air with water creating a column of millions of tiny microbubbles. These tiny microbubbles provide an enormous surface area for the absorption of organic compounds and waste products. The unique impeller plates remain ridged during the rotation, pushing more water and increasing contact time while still hacking those bubbles into a dense foam froth. Mixing injection system creates up to 3 times the amount of microbubbles and contact time compared to needlewheel type skimmers.

The foam collected by the skimmer is made up by protein and other organic compounds. These organic wastes must be removed before they turn into nitrate and nitrite. The fine bubbles produces by the skimmer also helps to increase oxygen dissolved and ORP (oxidation-reduction potential) level.
