Alright so after looking for nano ideas my mom suggested I ask the guy who I sold my original 29 to a couple years back. Well... perfect timing because he needed some $ for a bike and I needed the tank! Got it for $50 with the sapphire aquatics original biocube skimmer, 3 pumps, heater, refractometer, stand, salt... needless to say a good deal! So earlier today I picked it up cleaned it all checked for leaks and went out to get the live rock, got it all set up now and I need help with the skimmer in the back... for some reason it doesn't seem to be fitting right or bubbling weird, causing the pump to spray tons of bubbles into the main tank.
