I think it appears after water changes but it could possibly be related to feeding. It's a new tank and right now the specks are on all the glass surfaces but no where else and do mot move. They will go away in a couple days...thoughts?
it's a type of algae. i think it grows from the "aloe vera" thats in some water conditioners. i switched to safe and it went away. it was mostly from using stress coat or amquel plus.
