Do algae scrubbers really work?
Yes. By providing a perfect environment for algae to grow inside the device, they starve the algae in your main display tank of nutrients.
Are turf scrubbers worth it?

How long do the LEDs last?
The high-efficiency LEDs in the 2026 model are rated for approximately 50,000 hours, though performance may slightly degrade after 3–5 years.
