oxygen

How Do I tell if I am getting enough O2? I have a 30 gallon tank with 30 lbs of live rock and live substrate. I am using Korilia 425 and 550, the 425 is pointing at the surface and the 550 pointing at the live rock. I am frustrated/confused

Are you observing any symptoms of oxygen deficiency in the tank?

As long as you have sufficient water movement (those two powerheads in a 30 gal is enough) and you have sufficient water surface area there should be no issues with oxygen in the water.
Conversely, those same mechanisms also cause CO2 to be expelled from the water and back into the air.

What symptoms would I observe? I just notice that my clownfish is hanging at the same area at the top of the water.

What are your water perimeters and other livestock?
