Anyone here using this skimmer?

I finally got mine today and I am a little confused. I got the Mag Drive
upgrade (Mag 3) and the water is literally SHOOTING out the side of this
thing. (the skimmer, not the pump)

I guess my main question is, how does the water normally discharge.

I opted for the drain fitting so there is a groove cut down the side to
allow it to fit. Other than that, there is no where else for the water to
go. (drain fitting is on the collection cup)

I actually cant use this now because the water would be splashing out of my
sump. This doesnt seem right so I wanted to hear from others who use this
product.

TIA
