Pondlith: treated Zeolite grains: 2.6 kgs treats up to a 2600 litre pond
	2.6kg in 20 x 20 x 12 cm basket. Zeolite based natural product is a high performance, proven filter material thanks to its crystalline surface , which is a 1000 times greater than sand. The large surface area promotes settlement of micro-organisms and hence the breakdown of toxic ammonia that occurs through fish waste and unconsumed food. It also withdraws the nutrient base for green algae and thus prevents turbidity. Effective for 125 days after first use, can be recharged with pond salt rinse. Sufficient for 2600 litre pond without fish, 1300 litre goldfish pond, 650 litres Koi pond.
