The Ecoflo biofilter from Premier Tech Aqua is offered as a nitrogen-reducing unit, thanks to an add-on kit comprised of a pressurized flow divider, which recirculates a fraction of the water back to the primary tank, and a simplex control panel, which manages the dosing pump cycles and monitors all records. Available in ready-to-use roto-molded shells or as a kit to be integrated into existing tanks made by local precasters, this ecological, high-performance and low-maintenance unit uses a 100 percent natural and compostable coco husk-based filtering media. 717/479-0005; www.premiertechaqua.com; Booth #4112.
