|I have 0.4 copper in my pool currently. I am treating my pool for almost 3K ppb phosphate now. I used a sequestering agent a few weeks ago (Bioguard/SparkleUp) and then cleaned the filter with no reduction in copper. Do I need to add another sequestering agent to the water when I add the culator 4.0 in? My pool is about 31K gallons. Thanks for any advice!
Thanks for the questions. The sequestering agent will last about a month. Just place the CuLator Ultra 4.0 into the pump basket and leave it in all summer. You should be good to go!
