On my new 20 gallon w/ 45 lbs of LR and 20 lbs of LS, I use a Emperor 280 for filtration. Since I started it 4 or 5 days ago, I have constantly had foamy bubbles all over the surface of the water. Anybody know what causes this? Is there some way I can adjust the filter to not shoot the bubbles or air into the water?
