Hello, I've been looking at the site for a couple of weeks now. Great stuff. I've changed my method to the BBB"s. My question is. Here in St. Louis, Mo. its been rainy for the last 8 to 10 days now. Its supposed to let up on Tues & Wed, but back raining Thurs thru Sat. When do you I check and add your chemicals to the pool? When all of this is over? I don't want to waste alot of chemicals ,but I also do not want my pool to get too out hand. Appreciate any help.
