The heat has come and with that comes a necessity for more chlorine. When the sun begins its trek across the summer months your pool will need more chlorine on those weeks of intense UV exposure to the pool. The ultraviolet rays of the sun burn chlorine out of solution at a very fast rate thus requiring more chlorine on a regular basis. For those of you who use salt systems, turn up the cell 10%-20% so that you don’t end up with a moment where no sanitizer is being administered to the system. For customers who use liquid shock and tablets, you will want to open your chlorinators up a notch or two to generate more chlorine flow through the unit and you may want to start shocking the pool a little more frequently. If you shock the pool once every 7-8 days you may want to up the ante and start shocking once every 5 days so the pool doesn’t bloom with algae. Basically, if you have any doubts about the chlorine level in the pool, your safest bet is to test the water for chlorine and if the level is low, shock the pool to keep it from turning green with algae.
