Is there more general advice for closing a pool in more mild climates? Our pool is not heated so is not really usable from March-April to October-November. Melbourne averages 14 degrees celsius in winter but closer to 6 at night. Our pool guy advised us to add a particular algicide that lasts for 2-3 months, put the cover on and forget about it. Does that sound okay? You'd still want to keep the chlorine levels up right? Could you use chlorine tablets and just test occasionally?
And then I'm guessing you would SLAM when you open the pool for use?
