The Clearwater Algae Scrubber is an external biological filtration device designed to grow hair algae in a controlled environment to export nitrates and phosphates from aquarium water. It is best for saltwater and freshwater enthusiasts who want a natural, low-maintenance way to outcompete nuisance algae in their display tanks. While it is highly effective at nutrient export, it requires an elevated mounting position and a dedicated feed pump, which may not fit all sump configurations.

Despite the name, this is not a handheld tool for cleaning glass; it is a specialized aquarium filtration system known as an Algae Turf Scrubber (ATS).
Typical use cases include:
- Saltwater Reef Tanks: Controlling nutrients to prevent “ugly stages” or hair algae outbreaks.
- Freshwater Systems: Reducing nitrate buildup in heavily stocked tanks.
- Refugium Alternatives: Providing high-capacity nutrient export in a more compact footprint than a traditional macro-algae refugium.

In testing, the Clearwater unit shows consistent results based on nutrient levels:
- Strong on Light-to-Moderate Nutrients: Excellent at maintaining a stable, low-nutrient environment once seeded.
- Struggles with Heavy Initial Buildup: If your tank is already overrun with algae, a scrubber takes 3–6 weeks to fully “seed” and begin making a visible impact.
- Depends on Flow and Light: Performance is highly sensitive to the flow rate and the duration of the lighting cycle. If the flow is too low, the screen may develop uneven growth or “dead spots.”
