Siporax ceramic rings apparently great for achieving low nutrients

Frag section , you always have extra frags .

I planned to have a frag section but now my space is taken up with a huge skimmer. Live rock and a CA reactor

They don't get plugged up like bio balls?

Not if you stack them in a egg crate box (homemade)

I loled :lol:

I'm now thinking I'd like to put something in there that would provide live food for the main display. Something like a shrimp pair.
