I just ordered a Marineland C-220. Got it shipped for $89 which I thought was a decent deal. Anything you C-220 owners can share with me that I might want to know prior to arrival? What are your overall thoughts on the filter? I plan on chucking the bio balls and will run the sponge mech media, then floss, then floss and 100 ml bag of purigen, then floss and ceramic and matrix mix. I plan on putting a sponge prefilter on the intake.
