i'm running my pump at night. bad idea ?

[aylad]

in an attempt to stop the sun from burning out so much chlorine, i thought
that keeping the water still during the day might help. so i run my pump 6:00PM to 6:00AM instead of during the day.
(CYA is 50. I keep my chlorine between 3 and 6 as per ben's chart)

so
1. does this even make sense to do ?
2. pool guy has warned against this saying it would promote algae.

thanks in advance

In addition to the discussion above in answer to your question, just thought I'd throw a thought in, too... during the hottest part of the summer (remember I'm from Louisiana) I sometimes run my pump at night instead of during the day, too, because it helps cool the water and keep the temp lower...so the pool doesn't become a huge hot tub.
