I think that since the sand is clean in the morning and then browning by the end of the day this points to dinos. Hopefully others with more experience with this will weigh in soon.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!
That would make sense. I initially ruled that out because I naively thought dynos were a “new tank” problem but on further research it seems likely that’s what it is. Thanks for pointing me in the right direction. Maybe my nitrate value of 2 is causing this. Or my recent chemiclean blast of a cyano outbreak. Man this hobby can be frustrating at times!
It certainly can be!!!! Chemiclean can certainly do it. And yes, raising nutrients a bit should help.
