Koi Carp Owners Going Green are turning to Euro-Matic Pool Insulation Balls as an effective and eco-friendly way to maintain their ponds and pools year-round. Traditionally available in natural and translucent blue, these insulation balls now include a much-requested translucent green variant — introduced due to high customer demand. This new color blends beautifully with existing blue balls to create a water ripple effect that’s both functional and visually appealing.
By simply pouring Euro-Matic Pool Insulation Balls onto the water’s surface, they conform effortlessly to any shape, covering over 91% of the area. This layer helps reduce heat loss, limit evaporation, and allow natural oxygen exchange to prevent stagnation.
For pond enthusiasts — especially Koi carp owners going green — these balls provide a unique advantage. They help maintain a consistent water temperature, which is vital for koi health. When the water stays above 10°C, koi remain active, eat regularly, and continue to grow throughout the winter. If temperatures drop below 4°C, it can be life-threatening. The translucent design of the balls allows sunlight to pass through, creating a well-lit, stable environment for the fish.
A standard 6m x 10m pool heated to 25°C can lose up to 30,000 BTUs per hour in 18°C air. Even the best-insulated pools lose most heat from the open surface. Insulation balls reduce surface heat loss and cut evaporation by up to 90%, saving up to 75% on energy bills.
Installation is quick — just pour them in during winter and scoop them out for summer storage. Unlike bulky winter covers or structures, insulation balls preserve the natural look of the pond or pool.
