Hi there,
Thank you for reaching out with your question.
I contacted Vertex on your behalf and they have let me know that the diameter of the collection cup is approximately 250mm or 10 inches.
Please let us know if you have any other questions!

I am setting up a 210 gallon with 60 gal sump. Will this skimmer be overkill? I plan to slowly add sps and lps. Space in the sump won't be a concern.

Great question!
if the tank has an initial light bio-load the skimmer will be a little tricky to tune in. however if the bio-load is heavier this skimmer will work great!
