Calcium reactor used for biopellets ok?

[Zeither18]

I have a geo reef 1218 calcium reactor that I currently have no use for at this time ( I have very few corals) could I use this for biopellets for the large fish bio load I'm wanting to have Or would it be way to big? I have a 220g with 200 lbs of dead rock that I just recently started back up 3 weeks ago and am just curiouse for the near future
