MARIMEX Filter balls AQUAMAR BALLS 450g

The universal Aquamar balls Marimex filter filling is the ideal replacement for sand in your pool filtration system. The filling consists of polyethylene foam balls with a diameter of 55 to 60mm.

What's more, they can be washed in a standard washing machine and reused. The package contains 450g of balls, which is equivalent to approximately 17kg of sand.
