• Clear Water You Can See: Integrated 18-Watt UVC clarifier wipes out green water and floating algae for a beautiful, balanced pond.

• Simple Plug-In Setup: Just connect a submersible pump and return line — no complicated plumbing or extra parts required.

How a Surge Filter Improves Water Quality
The Evolution Aqua Surge Pond Filter uses patented air-powered cleaning cycles to flush away waste in minutes. No teardown, no cartridges, no foam blocks — just quick, low-effort filtration any homeowner can manage.
• Fast Monthly Cleaning: Open one valve and let air agitate the media to release waste and drain dirty water.
• Save Time Every Season: Less frequent cleanouts mean more days actually enjoying your pond instead of working on it.
• Waste-Smart Draining: Clear waste hose shows debris leaving the filter, so you know when it's clean.
• Energy Efficient Filtration: Uses air, not motors, for cleaning cycles — saving electricity long-term.
• Garden-Friendly Disposal: Wastewater can be used to water plants, keeping nutrients in your yard rather than the landfill.
