generate chlorine overnight or during the day | Latest Forum Discussions

I really am bewildered by this concept that chlorine added/generated during the daylight can disappear virtually immediately?  Does this mean we should be running the SWG mostly at night?  If this is the case then my pool pump will be running virtually non-stop all summer.  Because if i want my pool heater to run i start my pump early in the morning so by noon the pool is up to temp.  I always thought running the heater overnight was a waste when temps are lower.  I have a heat pump.  the ambient heat makes a massive difference on the energy needed to warm the water.  if i run the heater on while 10, 15 degrees warmer during the day vs overnight the water it heats the pool faster.  Now, back to chlorine.  If i run my pump overnight for the SWG to work,  then i run the pump during the day to get the pool hated, my pump is never really ever off then.

so i'm bewildered.. should we be generating chlorine during sunlight or overnight?    (yes i strive to have my CYA at the correct level).
