Just buy a house that has a "beautiful" green pool. I live in Vancouver, new to the pool but have done some research about clean the maintain the pool. But the house will be left empty over the winter until spring. My question is shall I start to the turning green to blue process now or leave it until I come back?
Also how long should I keep the pump/filter running daily? Can I turn it off if I am away? The filter is Haward sand filter, it seems quite costly the electricity if keeping running all day.
