50mm Green Pool Insulation Balls

50mm Green Pool Insulation Balls are the smart way to reduce heat loss, evaporation, and energy bills in koi ponds and swimming pools. Designed to float as a flexible cover, they adapt to any shape of pond or pool, creating a protective layer that is effective, attractive, and maintenance-free.

For Koi Ponds

Heating koi ponds through the winter can be costly. These insulation balls cover more than 91% of the water’s surface, reducing heat loss by up to 75% while still allowing oxygen exchange. This prevents stagnation and keeps fish active, feeding, and growing even in colder months. The balls also lower ice formation by up to 10°C, helping to safeguard valuable koi from freezing conditions.

For Swimming Pools

Whether indoors or outdoors, the benefits are clear. In indoor pools, the balls help reduce condensation on walls and ceilings. Outdoors, they minimise evaporation by up to 90%, saving water as well as energy. Unlike bulky pool covers, you can swim directly through them, and they even help reduce splashing, keeping more water in your pool.
