Features

• 20,000 LPH High-Velocity Output: Designed for rapid oxygenation in large bodies of water, supporting high fish stocking densities.
• Push-Flow Explosion Technology: Creates a powerful underwater current combined with millions of micro-bubbles for maximum gas exchange.
• Heavy-Duty Vortex Impeller: Engineered to handle continuous operation while resisting clogs from debris or organic matter.
• Energy-Efficient 200W Motor: High-performance copper-winding motor provides industrial-grade pressure with optimized power consumption.
• Directional Flow Control: Features an adjustable nozzle that allows you to "push" water in a specific direction, facilitating a circular "river-like" current for fish exercise and waste management.

Applications

• Placement: Position the COF-20000 at least 30–50 cm below the water surface for optimal oxygen-to-water mixing
• Mounting: Use the weighted base to secure the unit on a flat surface or a raised brick to prevent it from sucking in bottom sludge.
• Air Intake: Ensure the air intake tube remains above the water level and is protected from rain or clogging debris.
• Angle Adjustment: Aim the nozzle toward the surface or a "dead corner" to establish a consistent circular flow in the pond.
• Operation: Connect to a GFCI-protected outdoor outlet. The unit is designed for 24/7 continuous operation.

Usage

• Large Koi Ponds: Provides the critical dissolved oxygen levels required for large, high-value koi during summer months.
• Fish Farming (Aquaculture): Increases survival rates in high-density breeding tanks or grow-out ponds.
• Algae Control: Strong current and high oxygen levels help prevent the growth of anaerobic algae and foul odors.
• Waste Management: Pushes solid waste toward the bottom drain or filter intake by creating a directional "river" current.
• Ice Prevention: In colder climates, the constant water movement prevents the surface from completely freezing over, allowing toxic gases to escape.
