I won't use my pool for swimming from Oct. to May next year. A pool guy told me to treat the pool as normal in the off season, i.e. 3 hrs pump running, add bleach and do weekly maintenance. No other special treatment needed as the local temperature never drops to the freezing point. Just wonder if there is any more economic way to reduce the maintenance time and cost. For example, can I just trow a lot of chlorine into the pool and cover it up, shut down the pump and leave as is to next spring? Thanks.
