Yes, the last two months, my pool has had zero chlorine in it. However, not every pool will be able to do this. It really depends on how much stuff drops in the pool over winter but algae had very difficult time growing in cold water so for most pools it is ok. I test PH about twice a month but it does not seem to change much. CH I don't bother with since there is not much I can do about it anyway (mine is always high).
