The New DYMAX LS Skimmer violently mixes air with water creating a column of millions of tiny micro bubbles. These then provide an enormous surface area of adsorption of organic compounds and waste products. The unique impellers plates remain ridged during rotation, pushing more water and increasing contact time while still hacking those bubbles in to a dense foam froth. Mixing injection system can create up to 3 times the amount of micro-bubbles and contact time compared to other needle-wheel type skimmers.
This unit features two unique installation methods allowing for either hand-on or in-sump techniques. The mountain brackets fit virtually any tank with a lip of 1.5" or less and can be secured with integrated nylon screws. Water tight pump unions provide easy removal for cleaning and maintenance. Simply connect the skimmer inlet to a power head or existing plumbing line, adjust the water flow to the correct flow rate and skim-away!!
The LS Skimmers are built for performance with unprecented precision to detail. Cell-cast acrylic body and clean moulded connection parts to make it a unit that will provide years of outstanding performance. The collection cup is easily removed and has a rubber grommet connection assembly that ensures a snug fit. A fully adjustable flow valve completely allows you to control the water height within the skimmer body-maximising foam collection. Also the mixing-injection system includes an air silencer to keep things quiet and peaceful.
