I assume the air is coming from the the holes in the piping of the overflow. I've attached a video below of the set up, any help/advice is appreciated!!

The video shows the intake that has three small holes and an intake covered by an a grate. Water is just flowing through the holes, so I'm not sure what the larger grated intake is for.
Ours did this too. It sounded like a toilet flishing alllllll the time
. We went about it the way some people say you should not
. We put a ball valve in to control the flow. Before that, we made a U trap out of the hose that we had to create back pressure. I will flush the ball valve once a week to make sure it does not get too cruddy.
