Our range of Aquarium Algae Scrapers offers professional tools for effective and fast removal of stubborn algae (including diatoms and Black Brush Algae) from glass tanks. The Stainless Steel (SS) Body options provide durability, weight, and long reach for deep tanks, with both Regular and Wide Blade heads for precision or speed. The Plastic Body scrapers are budget-friendly alternatives, ideal for quick maintenance in smaller tanks. All blade models use safe, easily replaceable razor blades to eliminate the toughest algae build-up, leaving your glass crystal clear. Use with caution on acrylic tanks; strictly for use on glass aquariums. Replacement blades are also available in a Large Blade Refill Pack.
