Don't know why

[bizzleb01]

I have a euroreef skimmer, not sure the exact model, but it's worked really great since I got it. About two weeks ago it started foaming and my return pump is blowing the little bubbles into my dt.
I unplugged it and I used red slime remover and kept it off for about a week. I've done my water changes since using the remover and all parameters are good and the slime is gone.
I went to plug it back in today and it's doing the same thing. Anyone know why it would be doing this and how to get it to stop. I've been keeping it unplugged for now, but need to start using it again.

My RS100 puts out a little bit of micro bubbles, but they are either caught by the cheato or dont make it through the baffles. Are you saying that it puts out a LOT of bubbles? Im a little confused.

All skimmers produce a little bit of bubbles, but they should be caught before getting to the return.

Yeah, it puts out a lot of bubbles all of a sudden. Enough that they get blown into my dt and make everything kind of cloudy. I'm wondering if maybe I have a bad seal or something and it's letting in too much air?
