in my new tank, there are a ton of bubbles in the main and in the sump.
the tank is a 72 gallon reef ready bow front.
the sump is a 20H aquarium that has about 10 gallons of water in it.
the return pump is a mag 7 and it's hard plumbed to the main tank.
when the water comes out of the overflow into the sump it goes into a little trashcan that has holes drilled throughout the botom and then into the sump. The trashcan sticks into the water about 2.5 inches and hangs on the aquarium, It has filter pads in it. there is no splash plate so the water runs directly onto a filter pad and then into the sump. The holes in the trash can are completely submerged.
the water runs through the sump where there is about 25lbs of LR
then returns to main.
any ideas on what is causing the bubbles? The tank is 1 week old so I am not to terribly concerned about it, but t is a probem i would like to fix before I start adding livestock.
thanks in advance for any help!~
