I just set up a new 40 gallon tank with a 250w hqi pendant. I noticed some little bubbles just under the surface of its tissue. When I touch them or wave water at it some of them come out. It was under a 65watt pc before this. The pendant is about 16 inches or so above the tank and the brain is in the sand on the bottom. Is this because of the lighing? Any info would be appreciated.
