PENTAIR 9'' Metal Back Stainless Steel Bristle Algae Brush
Product Overview
Pool techs reach for the Pentair 9-inch stainless steel brush when standard nylon bristles fail to dislodge stubborn black algae or mineral scale on plaster surfaces.
This heavy-duty brush features stainless steel bristles securely set in a reinforced metal and ABS-aluminum frame, providing the mechanical leverage needed for aggressive scrubbing. Unlike wider brushes that lose pressure across the surface, the compact 9-inch width focuses your effort on specific problem areas like steps and corners. It is a proven choice for maintaining gunite and concrete pools where deep-set organic growth requires more than just chemical treatment to fully eradicate.
Benefits & What Makes It Different
Stainless Steel Bristles
These abrasive bristles are designed to dig into the porous texture of plaster and concrete to physically remove black algae roots that nylon cannot reach.
Reinforced Metal & ABS Frame
The combination of a metal back and ABS-aluminum frame prevents the brush from flexing or snapping under the high pressure required for heavy scrubbing.
9-Inch Compact Profile
The narrower width allows for precise control and higher PSI on the surface, making it easier to clean tight radii and step corners where algae often hides.
Compatibility
- Safe for Plaster, Gunite, and Concrete surfaces
- Not compatible with Vinyl liners, Fiberglass, or Painted surfaces
- Fits standard 1-1/4 inch telescoping poles
When To Use This
Pro Tip
For black algae, use this brush to 'crack' the protective waxy coating of the algae colony before applying a granular trichlor spot treatment; this allows the sanitizer to penetrate the roots directly. Whether you’re dealing with tough black algae or just need a reliable scrubbing tool, this mechanical prep is essential.
Common Questions & Instructions
Can I use a stainless steel brush on a vinyl liner pool?
No, stainless steel bristles are highly abrasive and will puncture or tear vinyl liners and scratch fiberglass finishes; this tool is strictly for plaster, gunite, and concrete surfaces.
How do I know when it is time to replace my algae brush?
You should replace the brush when the stainless steel bristles begin to thin, break off, or lose their stiffness, as worn bristles won't provide the necessary friction to dislodge algae.
Will this brush fit my existing pool pole?
Yes, the Pentair 9-inch brush features a standard snap-adapt handle connection that is compatible with almost all universal 1-1/4 inch diameter telescoping pool poles.
