It is the time at which we used and enjoyed the swimming pool totally. At this time we cannot neglect to control the swimming pool periodically. It is necessary to remember that it is at this time when it is more difficult to be able to maintain the swimming pool in good conditions. The excess of heat, the solar radiation, the excess of swimmers and the summery storms, are cause of imbalance of Ph and chlorine levels that can be very easily spoil the water of our swimming pool. In this period we will consider the following observations:

• To control of chlorine and Ph.
• To control of turbidity
• To clean the bottom
• To control of automatism of the ignition motor
• To add chemical agents necessary to guarantee the hygienic healthful conditions of the water of the swimming pool.
• To review that all the installation is in perfect conditions: absence of losses of level of the water or dripping in the installation.
