Buninyong, Victoria, Australia Jan 16, 2025 Add bookmark #7 I’m not familiar with your “purging”chemicals as I only use AhhSome for purging. I just utilize a microfiber towel to wipe off any gunk (biofilm) in the acrylic before the gunk dries. The S200 cleans just in addition to the S300 https://www.profi-poolwelt.de/edelstahlpool/
