Old tidepool biowheel

[EricGubricky]

I have an old tide pool bio wheel sump that I want to set up on a new tank, (long story, My tank stand is built in and it's the only thing that fits.) My question, should I ditch the actual bio wheel, and fill that compartment with live rock or Marine pure bio media?

I’m not familiar with that sump. Is the bio wheel in place of filter socks?

Water goes in the top, through 3 filter trays, over the bio wheel (small compartment), then flows into the big compartment where I have my skimmer, heaters, and return pump.
