My husband of the year :-D has our new 18 x 54 Sharkline Matrix pool up and running. I have been in charge of Pool school. Water truck showed up at 8 pm Friday night and filled the pool. I used the pool calculator and added 71 ounces of bleach so we could swim yesterday. We forgot to add the dichlor last night-only to be used for the next 4 days per pool school. I tested the chlorine and PH with my taylor K-1000-dailey test kit- and the results are spot on. Want to start adding the dichlor. How soon can we swim today after we add the dichlor?. I will update my signature and post the pictures of the pool construction. Love BBB :-D
