large bubbles going into sump?

[tjc348]

I just setup my sump today and I have alot of bubbles going into the sump (coming from the overflow). These are pretty large bubbles, almost like air pockets and they are really loud. Not sure why this is?

I have an Eshopps overflow,and have a flex pipe going from the overflow to the sump. My sump is beside my aquarium, and the flex pipe does have a little slack, almost like a droop.

Anyone have advice?

Make sure the flex pipe doesn't go down and start to curve back up. And research a way to put an air trap in your overflow like a durso or something. Might just have too much water running though it if that doesn't help.
