Hello all.
We've reached that time of year when the solar panels are not keeping the pool above 21°C (70°F) so I'm thinking about shutting down for the winter. Some threads on TFP advise "close late, open early" which is the opposite of what I've always done. So what if the pool water is green when we open? There's always the SLAM to take care of that.
Does anyone seriously advise leaving it open well into Fall, and continuing daily testing as well as adding 1-2L of 8.25% bleach every day? I'm thinking that for next year, a CYA level of 40 might be preferable to the 30 that has been my target this year, thereby lessening the bleach requirement.
FWIW, we live in a part of Canada where freezing is rarely an issue. We do on occasion see a layer of ice form on top of the impermeable (sort of) winter cover.
