I was wondering if the rubber tubing was supposed to be in the water in the sump or outside sucking up air

Brand new....? Run it like it is for now. It'll take a bit to break in. Some people just take the lid off and let it overflow for the first day or so until it settles down. Biggest mistake I made when I started, was not to account for changing water levels due to evap in the sump (I don't have an ATO). I was constantly tweaking it, and never realized that my issues were due to not being within the recommended water height.
The water level should stay the same in the skimmer area of the sump. The water level lowers in the return area. That is where I have mine marked and do my top offs.Brand new....?

Well... I have an old sump. I can't say that there really is a design to it lol. My "skimmer section" isn't big enough for my skimmer. The bulk of my sump is open and that's where I have my return and skimmer, hence the fluctuation in water level.Im not sure how your sump is designed, but the level in the skimmer section should be stable and never fluctuate. the evap, usually affects the return area which is isolated from and sits lower than the skimmer section with a baffle. Im guessing its a DIY sump, but you may want to consider "fixing" that....

Oh.... I know! I really want a 6 foot, custom sump! lol. I'm in the process of upgrading to a 240g and a new sump is next on the list. I don't think the custom will be a reality though.yup, that makes sense. think about a redesign. you really want the water level in the skimmer section to stay constant.
