I have a 2G bowl with some Java fern and Anubias without a filter or heater. Its been about a couple of weeks and now there is a fine layer of this brown dust algae (I forgot the name) on the top of the leaves. What would be the best way to control this and not have to rub it off with my fingers to clean it? So of it also forms on the glass. Would ferts or more light help?
TIA...
