I'm in North Canton and have started my opening. This week, I have just been letting the water circulate, brushing and adding chlorine every day. This weekend, I will start vacuuming, and slamming. Right now, I have quite a bit of dead algae on the bottom. FYI… Ollies has Liquid Shock for $2.99 a gallon and Great Escape has it for $14 a case of 4 gallons. If you received the coupon in the mail from Ohio Pools, $11.96 a case.
