I am in that boat. By week's end the dust is starting to be noticable on the glass, but it's okay. I wipe it off, do a water change, and it's gone for 5 to 6 days.
I don't suffer any other algae, and dosing Flourish Excel doesn't seem to have any impact on green dust algae.
I figure it's something I have to live with, especially since nobody seems to have a prescription for how to get rid of it.
I can't imagine washing out a tank with bleach would help in the long term, given that the bacteria for green dust are in the air we are breathing right now. |
This can be fixed by slightly increasing your PO4 dosing. While the ideal ratio of Nitrogen to Phosphorus in a planted tank is about 10:1, your dosing should not be 10:1. Dry dosing a ratio of 3:1 to achieve the desired levels of each nutrient.
Also, Olive Nerite snails will do a tremendous job of cleaning GDA off of the glass.
