first off, Kudos for severum mama for correctly advising you to run both filters for 2 weeks to avoid a mini-cycle.
Aqua Clears don't use a bio-wheel...you cannot hook one up.
For the record, I too ONLY use aqua clear HOB
's for smaller tanks. They clean easily, the motors are cheap if you happen to burn one out, and the filter media chamber is the most customizable HOB
on the market. I've run bio balls and filter floss in them, but normally i just use 2 sponge blocks, no carbon, no floss, nothing...
