This helps eliminate green water (algae blooms), controls floating bacteria, and reduces the spread of free-swimming parasites.1400 LPH Flow Rate: Provides strong water circulation, ensuring efficient turnover and oxygenation for tanks up to 4 feet in length.3-Stage Filtration: Features three large-capacity media baskets that can be customized with sponges, bio-rings, or chemical media.Self-Priming Pump: Includes a convenient priming button on the lid that eliminates the need for manual siphoning when setting up or after maintenance.Dual Control: The UV lamp can be switched on or off independently of the filter pump, allowing you to use it only when needed.Maintenance Note: To keep the UV function effective, it is recommended to replace the UV bulb every 6–12 months, as its intensity diminishes over time even if it still appears to be lit.
