My tank was set up March 1, 2010. I used about 20lbs of live rock from my old tank. I have been using Microbacter 7 since setting up the tank. The first two weeks I followed the directions recommended for tank start up. Afterwards I followed the directions for maintenance. I currently have a Yellow Tang, a Flame Hawkfish, a Bicolor Pseudochromis,and a Ocellaris Clownfish. Ammonia, Nitrites, and Nitrates are at zero. My skimmer (GSA GS1) is not producing any skimmate. It produces very little foam. If I close the valve enough I can get it to produce enough to flow into the collection cup, But it is very wet. Should I be producing more foam? Could it be that because the tank is so new there is nothing to remove at this point?
