Livewell Fish Tank Vent

Problems This Product Solves

• Fish Suffocation During Transport: Continuously supplies fresh oxygen-rich air into the livewell, preventing oxygen depletion that causes fish to die during long trips.
• Toxic Gas & Heat Buildup: The dual-channel Venturi design actively exhausts harmful gases (CO₂, ammonia) and excess heat from the tank while drawing in fresh air simultaneously.
• Rising Water Temperature: Continuous airflow helps regulate water temperature inside the livewell, reducing thermal stress on live fish and bait.
• Dependence on Electric Aerators: Works passively using natural airflow and the Venturi effect — no electricity, no batteries, no maintenance required.
• Low Fish Survival Rate: By maintaining optimal oxygen levels and temperature, this vent significantly improves live fish and bait survival rates during transport and storage.
• Difficult Installation: Simple screw-mount design fits standard livewell openings — installs in minutes with included hardware.

Key Features

• Dual-Channel Venturi Design: Two separate airflow channels work simultaneously — one draws fresh oxygen-rich air in, the other exhausts stale air, heat, and toxic gases out.
• Passive Aeration — No Power Needed: Harnesses natural wind and vehicle motion to generate continuous airflow using the Venturi (Bernoulli) effect — zero electricity required.
• Thickened ABS Construction: Reinforced ABS material resists impact, saltwater corrosion, UV exposure, and cold temperatures for long-term durability.
• Oxygen Supply + Temperature Control: Simultaneously increases dissolved oxygen and reduces water temperature — the two most critical factors for live fish survival.
• Easy Installation: Standard round mounting flange with screw holes — fits most livewell and fish tank openings without modification.
• Available in Black & White: Choose the color that best matches your boat's deck or livewell lid.
