Pole Extended Pool Blok
Product Overview
What pool techs reach for when stubborn calcium line deposits require extra reach without draining the pool.
Manufactured by United States Pumice Company, the Pole Extended Pool Blok fits standard 1-1/4-inch telescopic poles to scour away hard water scale, calcium buildup, rust, and algae stains from pool tile and concrete. Its chemically neutral, 100% natural pumice stone wears down uniformly to conform to tile contours while protecting hard surfaces when kept wet. It eliminates the need to bend over the coping or enter cold water to detail the waterline.

Benefits & What Makes It Different
Standard Pole Compatibility
Snaps directly onto standard 1-1/4 inch telescopic poles so you can clean tile lines and deep-end steps from the pool deck.
100% Natural Pumice Formulation
Chemically inert material breaks down calcium, scale, and algae without altering your water chemistry or damaging glazed ceramic tile.
Restores Hard Surfaces
Safely scours gunite, plaster, and concrete surfaces by wearing down gradually to match the surface profile without harsh acid washing.

- Ceramic tile, porcelain tile, gunite, concrete, and unpainted plaster
- Not compatible with vinyl liners, fiberglass, acrylic, or painted pool surfaces
When To Use This
Pro Tip
Keep a bucket of pool water handy or submerge the stone before touching the tile line; dry pumice can scratch glaze, but a saturated block acts as a self-lubricating micro-abrasive that shears off mineral crust effortlessly.
Common Questions & Instructions
Can the Pole Extended Pool Blok scratch pool tile or plaster?
When both the pumice stone and the surface are kept thoroughly wet, it will not scratch glazed ceramic tile, porcelain, gunite, or concrete. Never use it dry, and do not use on vinyl liners, fiberglass, acrylic, or painted surfaces.
How long does a Pool Blok pumice stone last?
Lifespan depends on the severity of calcium scale; pumice is a sacrificial abrasive designed to wear down as it cleans. A single block typically cleans 50 to 100 linear feet of moderate waterline buildup before needing replacement.
Does using a pumice stone affect pool water chemistry?
No. United States Pumice stones are chemically inert and non-toxic, meaning they will not alter pH, total alkalinity, or sanitizer levels during routine waterline scale removal.
