The Pond Guy AllClear G2 All Clear 2000 — Pressurized External UVC Biological & Mechanical Filter with Backflush and 9-Watt UV Clarifier for Koi Water Gardens

Three-stage filtration in a single pressurized unit — The AllClear G2 (All Clear 2000) combines ultraviolet, mechanical and biological filtration to polish pond water before it is returned to your pond. High-output, low-energy 9-watt UV clarifier — Pond water passes by a powerful yet energy-efficient 9-watt ultraviolet bulb that helps clear suspended algae and particles prior to entering the filter chamber. Mechanical and biological media — Inside the pressurized chamber, alternating low- and high-density filter pads trap debris while providing an ideal surface for beneficial bacteria to colonize. Simple backflush maintenance — Use the easy-clean lever by moving it up and down to flush accumulated debris, fish waste and other contaminants out of the filter pads. Ideal for new builds or established ponds — Designed for koi ponds, water gardens and outdoor fishponds, this unit is suitable as an upgrade for existing systems or as part of a new installation to help maintain crystal-clear water all season.
