How do you winterize a concrete inground pool with a marbelite finish to survive a Canadian winter?

To winterize a concrete inground pool with a marbelite finish for a Canadian winter, first, clean the pool thoroughly and balance the water chemistry, ensuring pH and alkalinity are at recommended levels. Lower the water level to below the skimmer, and drain all water from the Plumbing lines, returning jets, and pump. Add winterizing chemicals to prevent algae growth and cover the pool securely with a winter cover to keep debris out. Finally, ensure all equipment is stored properly and protected from freezing temperatures.
