Key Features

• Patented Air Clean Technology: Uses a unique air and water mixing process to agitate open-cell K+Media and dislodge trapped debris without the mess of traditional sponge filters.
• Built-In UV Clarification: Integrated 18-Watt UVC bulb helps eliminate green water and algae, ensuring a vibrant, healthy pond environment.
• Compact & Space-Saving: Its streamlined design makes it ideal for installations where space is at a premium.
• Complete Installation Kit: Comes with mounting brackets, stepped hosetail fittings (0.75", 1", and 1.25"), ball valves, and a clear drain hose so you can easily monitor wastewater flow during cleaning cycles.
• Virtually Maintenance Free: With a self-cleaning process that leaves your hands dry, the Surge Filter minimizes routine upkeep.

How It Works

Water is drawn from your pond by a submersible pump and delivered to the Surge Filter. Inside the filter, a built-in UV clarifier works to neutralize green water and algae. Simultaneously, air is drawn into the unit where it mixes with the water, causing the advanced open-cell K+Media to move chaotically. This agitation dislodges accumulated waste from the media, which then exits through the waste line at the bottom, returning clean water to your pond.

No more messy cleaning with sponges or foams – simply operate the ball valves to initiate a cleaning cycle, and watch as the filter self-cleans while your pond continues to run clear.

Filter Installation

The Surge Filter is designed for pump-fed setups. Install your submersible pump in the pond, slightly raised off the bottom, so that water is drawn from the pond and fed into the Surge Filter. Filtered water is then returned to the pond by gravity via a hose – either directly back to the pond or through a waterfall arrangement.

For optimal performance, ensure the flow rate through the filter is around 660 GPH and do not exceed 925 GPH. Make sure you have sufficient flexible hose length to connect both the pump to the filter and the filter back to the pond.

Once installed, simply turn on the pump to fill the filter with water. During normal operation, the inlet and outlet valves remain open and the waste valve is closed, while the UVC operates continuously to combat algae. When a cleaning cycle is initiated, the pump will shut off, the inlet and outlet valves will close, and the waste valve will open. Air will then agitate the K+Media to dislodge debris, which is expelled through the waste line. It is recommended to switch off the UVC if the filter remains empty for an extended period.
