I live on the West Coast in Vancouver, BC. We do not totally shut down the pool over the winter and I would like to know what chemicals I need to ensure are kept in check in order to best protect the pool equipment. We shut off the heat but keep the pump running 24/7. I know I need to make sure there is sufficient chlorine over the winter, but do I need to keep Calcium, PH, etc in check too?
Your assistance is greatly appreciated
