I have a 2 year old tank that looks amazing in the morning but by the end of the day each day is covered (not entirely but enough to be discouraging) in a brown-tinted algae of some type that I can’t identify or can’t seem to eradicate. My nitrates are at 2 and my phosphates are at .06. (Trying to slowly bring my nitrates up by dosing a nitrate additive.) I’m doing 10% water changes every 2 weeks with 0 tds RODI water. Any help would be appreciated!
