Duck Off Surface Tension Modifier – Eco-Friendly Pool Waterfowl Deterrent for Ducks & Geese

Protect Your Pool—Without Disturbing Nature

Duck Off™ by Spec Chem is a professional-grade, eco-conscious deterrent engineered to discourage ducks and geese from landing in your pool—without chemicals, harm, or disruption to your water chemistry.

This biodegradable surface tension modifier works by altering the cohesive forces at the water's surface. Waterfowl, which rely on a high surface tension to float comfortably, find the environment less stable and uninviting—encouraging them to relocate naturally. Duck Off™ is ideal for homeowners, resorts, and property managers seeking a humane, maintenance-free solution to bird-related pool contamination.

Key Benefits

• Scientifically Backed Action: Reduces surface tension to disrupt waterfowl buoyancy and deter landings.
• Non-Toxic & Eco-Friendly: Contains no harsh chemicals; safe for swimmers, pets, wildlife, and landscaping.
• Preserves Water Chemistry: pH neutral and phosphate-free; will not interfere with chlorine, saltwater, bromine, or mineral systems.
• No Foaming or Residue: Leaves water clear and equipment unaffected.
• Simple Application: Just dilute and pour—no complicated dosing or tools required.

How It Works

Waterfowl require a high-tension surface to remain buoyant and at ease. Duck Off™ temporarily lowers this tension, creating an environment birds instinctively avoid. There’s no physical barrier or distress—just a subtle, science-based shift that naturally keeps your pool bird-free.

Directions for Use

• Shake well before use.
• Dilute 1 quart of Duck Off™ with 1 gallon of water for every 15,000 gallons of pool volume.
• Distribute evenly across the pool’s surface, ideally during low wind conditions.
• Reapply monthly or as needed depending on bird activity.
• Do not use with hydrogen peroxide or PHMB (biguanide) sanitizer systems.
• Wait 48 hours after super-chlorination before applying.

Let your pool be a haven for people—not for birds. With Duck Off™, you maintain control over your outdoor space while respecting the natural world. Cleaner water, fewer droppings, and no more chasing flocks away—it’s a win for you and for nature.
