A new generation of filter balls, 700 gram filter balls, is enough to replace 25 kg of filtered quartz sand. It has an excellent filtration effect, a faster filtration speed and a larger collection capacity than conventional ones Filtration media. High water permeability made of 100 percent recyclable polyethylene with a diameter of 50 to 60 mm, washable, environmentally friendly and recyclable, long service life. Efficient filtration performance - Due to the higher filtration performance, the required filtration material is greatly reduced in order to achieve a clear water effect. With the easiest handling and weight that achieve the best result. Less backwashing is necessary and the environment is protected, also thanks to the reusability of the filter balls. Suitable for all commercially available sand filter systems such as swimming pools, swimming pools, filter pumps, aquariums, etc. You can effortlessly obtain an excellent filter effect. This hairball can also replace the filter sand. It is suitable for the filtration of filters, filter buckets, swimming pools, etc., which can effectively filter out fine suspended matter and improve the water quality. It is for the filtration of aquariums and aquariums, can replace the physical filtration of filter cotton and also replace the bacteria house.
