Not too bad, still have a slight look but nothing like it was. My tank did a "U" turn and I had bad BBA outbreak. I changed my bulbs, changed my CO2 cartidge and performed a 50% water change; all this did help. I did get a surface skimmer which I still need to install. There appears to be a slight dead spot inbetween my filters where water does move but very slowly. I think if I add the surface skimmer there, it will help surface movement; and water movement as well. I did start dosing on alternate days between micro and macro too. Reading back, I did a lot, lol. Thanks for asking.
