Recently have this algae covering my sand. Does not suck up through Python when I do my water changes rather it mats up. I can cover it by stirring the sand but it's back the next day. I'm almost positive it is algae and not cyano/dinos as I see my foxface pick at it constantly. It stays a thin layer almost exactly the same as the green film algae growing on my glass. Seems harmless but it is quite unsightly so I would like to get rid of it. Nitrates 8 phosphates .05. lighting blue leds 8-8 T5s 4-7pm. Daylight through windows 8-6.
Thanks
