Hello everyone. Just getting started here and my pool is currently being built. It is an 18X38 Grelian Vinyl SWG. 3 to 8 feet. What a mess in the back yard as it has rained 5 inches in Macon over the past 5 days. I will post more as the questions come to me and will be ordering the test kit everyone speaks about. I have been studying the Pool School and it has helped a bunch and will become a member soon. I did have one question the BBB system can be used in a Salt Water pool correct. Thanks and will post with all of the details when the pool is complete.
