I just wanted to get some clarity on closing an above ground pool for a Canadian winter. I read over the pool school article and it's quite clear what to do with the equipment and water level but no information on what to do with chemistry so that I am able to open to a clean and clear pool in the spring.
Am I safe to say that I should wait for the water to drop to temp of 15C before closing? At this point, I should do a good clean of my pool (brush and vacuum). Then balance alkalinity/pH. Adjust CYA to back up to about 40-50 then right before the cover goes on, add chlorine to shock level for the winter?
What should I expect at opening next season. Will there be any chlorine left in the pool to keep stuff from growing early spring, or is the goal to really open before the water gets above 15C temp?
