I'm joined today because I am going to use the BBB technique. I am frustrated with the pool store recommendations and tired of dragging six kids across town to get my water tested daily (store recommendations) by the ALEX computer only to walk out with $200.00 worth of chemicals that don't seem to do what I want them to do. I am excited to jump right in but need a test kit ASAP. I currently only have the dip stips from BIOGUARD (arrrgg). I need a test that tests Free Chlorine. The test at Walmart seems to only measure Total Chlorine Is there some deluxe test at Walmart that measure Free Chlorine or should I order one here? Any imput is appreciated!!
