i have a 125 gallon tank .. started it 2 months ago . i have 6 chromis,clown tang, and a Caribbean tang. the bubbles in the skimmer aren't reaching below the cup. they are halfway where the water comes into the skimmer ! is this because i have a low bioload ? i have the depth at 6-8 inches. The piece where you adjust the air flow is there supposed to be water in there ?any help would be appreciated .
thank you, mike
