Some INTEX pools (Ultra XTR Frame models over 457 cm) are also sold in a set with filtration combined with a saltwater system. The saltwater system can also be purchased separately if you already have a pump. Check the offer of your local dealer or online and pay attention to what is included in the package. The offered variants may vary. If you buy the saltwater system separately, pay attention to the connecting parts, the pump power that the saltwater system needs and the maximum volume of water for which the saltwater system is designed.
