REEF POSER
Just setup a new tank and started cycling.Got it up and running last night and im hereing a gurgling sound coming for the left overflow box its a 120 gal also noticed that the water level in that overflow keeps going up and down about 1 inch.Have 2 overflows and the right one doesnt do it. Any suggestions on what to do.Thanks. Running a mag 9.5 to one side and a Rio 3100 to the other. The side that makes the noise is the side with the uv sterilizer hooked up to it
