Hi all. This is my first post. I have a 12 gal cube that has been cycling for a few weeks. My numbers are all zero and my cuc is thriving. A friend dropped off two frags rubber banded to small pieces of lr.The frags fell off and I'm not sure of the best way to anchor them onto my rock. Is using rubber bands the best way or is there a better way. Thanks for all the help from everyone just by reading the forums. You guys are great. Rich
