To many bubbles!! Please help

OK, so today i looked at my tank and there was to many bubbles coming out of the return pump.. i cant figure out whats making that happen..
what should i do?

 

do you have a protein skimmer?

 

no. thats why im so confused. i checked the sump and there is enough water in there so there shouldnt be any bubbles. i cant seem to find the problem anywhere

 

make sure to check the intake around the impeller, sometimes they get so powerful they create a little tornado that pulls air in with it... also check for leaks as this would be a source for air

 

Your overflow might be pulling in air, are there bubbles in your sump?

 

im also getting bubbles in my tank so im see what other people say

 

nop not that i can see

 

Is it coming out of the return pump itself or out of the plumbing from the return pump into the tank? If it's coming out into the tank then it's possible you developed a small pinhole leak in your return plumbing which is sucking air into the plumbing.

 

Is there any kind of little water fall in system? This will produce bubbles.
