  • Publication number: 20240025783
    Abstract: An algae scrubber system operates via a flow of water and a power source. The algae scrubber system does not require a bubbler. The rate of flow of the water may be variable. The algae scrubber system includes a screen that is configured to be removed from the system without shutting off the flow of water through the system and without spilling the water. The system includes a main body with a water distributor providing water to a tray. A screen hangs from the tray to and grow light(s) encourage algae growth on the screen.
