Did the cap2200 come with the skimmer? I see the ad shows that it comes with a pump. If the cap2200 is not the one that came with it do you know the size of the pump that is packaged with the skimmer? Your profile says you have a 110gal tank. The ad clames this skimmer is good for tanks up to 75gal so that would imply that your skimmer is undersized for the tank. Of course you said you have the 150 model so its probably rated for something like 120 or 150 gal
tank. I like to half the manufactures recomendation for tank capacity so a 150 gal
skimmer capacity would be equivlent to a 75gal capacity for effective skimming.
Ozone can be dangerious to you and your corals if not properly configured. I would make that a last alternitive.
