Just put remora pro skimmer on 46 gal tank. Going to add 20 gal sump later but wanted to try it. Tank has only been running about 2 months. After 1st day small amount of light green liquid in cup. White foam. Seems to be more crud on surface than before. Only was using Aqua clear 300. Do I need to fashion a way to skim surface. I will add overflow box when I add sump. Also with skimmer on should I use Aqua 300 filter also? The micro bubbles from skimmer are getting fewer. Thanks
