HAEZU Copper Disk for Cattle Water Trough — 4" 99.99% Pure Copper, 0.6mm Thin with 4-Point Support

HAEZU's 4-inch 99.99% pure copper disk is a simple, durable insert that naturally reduces buildup in cattle water troughs and helps keep drinking water clearer between cleanings.

Small and fast to install, this 0.6mm-thick copper disk uses an elevated four-point support to expose more water surface to copper contact. Built for livestock waterers and troughs roughly 25–40 gallons (100–150 liters), the disc is designed to sit securely, resist tipping, and deliver month-long performance before cleaning or replacement is recommended.

How does the copper disk fit and stay steady in my trough?

The disk’s four raised supports lift it slightly off the trough bottom so water flows freely around and under it. That raised profile prevents the disc from laying flush and getting buried in debris while increasing the water that touches the copper surface, improving overall performance.

• Four-point support prevents rocking and tipping in uneven troughs.
• 10 cm (4") diameter fits standard small/medium waterers (25–40 gallons).
• Thin 0.6mm sheet keeps the disc flexible to conform without bending permanently.

What maintenance does the HAEZU copper disk require?

Routine care is minimal: the manufacturer recommends refreshing or replacing the disk about every 30 days to keep it working at peak effectiveness. For light-duty use you can remove and rinse it, for heavier gunk consider replacing the disc to restore full performance.

• Expected effective life per disc: about one month under typical conditions.
• For larger troughs (over ~200 liters), add additional discs for coverage.
• Simple removal and rinsing extend life; replacement returns to factory performance.

Will this work year-round in hot or cold climates?

The copper disk is engineered to function across seasons without special adjustments. Its metal construction tolerates temperature swings and continues to promote cleaner water circulation in both warm and cold weather.

• Metal construction remains stable in freezing and hot conditions.
• Design sustains 360° water flow even if ice forms at the surface.
• No power or chemical additives required—passive operation all year.

How many disks do I need for larger troughs or herds?

One 4" disk is sized for roughly 25–40 gallons (100–150 L). For bigger reservoirs or if you manage multiple animals that heavily foul water, install additional disks spaced across the container to keep contact area sufficient.

• Use one disk per 25–40 gallon volume for typical results.
• Over 50 gallons (200 L) generally benefits from two or more disks.
• Distribute disks evenly to maintain consistent water contact throughout the trough.

Who is this for? This HAEZU copper disk is aimed at livestock owners, small-scale farmers, and homesteaders who want a low-effort way to reduce slime and buildup in cattle water troughs. It’s particularly useful for those with standard-sized troughs (25–40 gallons) who prefer a passive, tool-free solution that installs in seconds and needs only monthly attention.
