Been fighting some brown hair in my tank, that's exactly what they look like brown hair. They don't get bubbly and don't look like snot. My snails do not die either. I tried h202 dosing with a 4 hour photo period, they went away only to come back a week later. I tried 48 hours lights out and dosed h2o2 followed by a water change, they went away for 5 days and now they're back. Here's a pic, the string coming off the bleached acro.
