Pool care and seasons

Opening, closing and everything in between, with the amounts worked out for your pool.

Good pool care is mostly routine: keep the water circulating, keep chlorine and pH in range, and keep debris out. The two moments that trip people up are the seasonal transitions. Closing a pool properly decides how much work the spring opening will be, and in freezing climates it protects plumbing and equipment from expensive damage.
