Auto water change waste water

[Spbk84]

Hello,

I am currently working on a garage conversion. I am making it into a living space for a 300 gallon aquarium. I really like the idea of a Stenner dual pump for auto changes. The tank will be on the opposite side of my laundry room where my utility tub is sitting. The copper lines and PVC are capped and almost ready to be tied in.

Some people suggested that I dump the water into the tub itself, but I rather not. Is there a special fitting I can purchase so the tank waste water can dump directly into the tub waste line rather than the utility tub itself?

Any guidance would be appreciated

Thank you

I'm thinking this DWV sanitary wye:

And if it's after the trap on the sink, you'll want to include a p-trap to make sure you don't have sewer gas coming back your way.
