Hi, folks. After the water truck leaves, what should I expect to need to do to the water? The pool is an 18' round, so about 8500 gal. I'm almost positive the water is coming from the city's municipal supply, so basically it's chlorinated drinking water. The pool comes with a "start-up supply" of chems, but I'm not sure exactly what that includes. I've read about SLAMing the pool before the first use and wanna make sure I have the chems on hand so I'm ready. I have a decent test kit already.
