I've setup a 180.5 and I can't get the sump quiet. The water spilling out of the religion through the top slots, about 13 inch water level. Spills into skimmer chamber, I have that set to the height of the spill over to the pump chamber. So the difference is about 5 inches, causing a loud waterfall. Should I raise the water level in the skimmer area? Seems like the proper level is where I have it. Open to suggestions. Thanks in advance.
