I just did my weekly PWC, and this stuff is a major PITA to remove...slimy and when I pull it off, only one or two strands at a time came off. Without killing the zoas, is there a way to do a mass culling of this stuff? I was able to get maybe half of it off... (FWIW, my 'trAtes are 0.2 and phosphates are 0.00)
