I've read elsewhere that the white stands on my stems are actually roots, is this correct? Also it seems that there is white fuzz on my hairgrass, does anyone know what this is and what I could do to get rid of it. The hairgrass seems to be in the phase where some parts die off and new roots & stems grow in. My tank (UNS 30C 7G) is two weeks old and am just starting to see nitrites and nitrates. (3ppm nitrite, 5ppm nitrate) and I haven't been dosing anything but Seachem Florida weekly.Thank you in advance.
