Light-dependent reaction. In the light-dependent reaction, light energy from the sun is used to split water (photolysis). which has been taken in by plants. Water, when broken, makes oxygen, hydrogen, and electrons. These electrons move through structures in chloroplasts and by chemiosmosis, make ATP.
Usually, we tell pool owners that between 8 and 12 hours is a good rule of thumb. Many people want to run their pool filter system only at night in order save on electricity during off-peak hours. That's not a bad idea, but it's not the best.
1 You may also want to add a high quality algaecide to the water at this point. 2  Run your filter 24 hours a day and backwash 3 or 4 times a day for quickest results. 3  Green or cloudy water will quickly clog a filter, therefore you may have to backwash your filter many times a day until the pool clears. The pool will never clear up if the filter is not working properly 2  ! Once the water does clear up, you will most probably see debris on the pool floor (dead leaves, algae, etc.). 3  If there is only a small amount of debris present, you may want to vacuum it up using your own pool vacuum system.
