Clean bathing water With the use of filter pumps you can clean the water. Yet prevention of dirt is always better than cure. Therefore the use of a pool cover is a very simple but effective solution for clean bathing water. This tarpaulin fits as cast to the Intex Metal Frame 400x200 swimming pool. Easy to attach The cover is easy to attach and then also stays firmly. The vinyl sail has an overlap of twenty centimeters so that the sail is firmly fixed over the edge. The sail can be tightened with the aid of the fastening cords. Due to the small holes in the sail the water can continue to breathe and there is no water floating on the sail. This way the sail remains of good quality for a long time.
