I'm going to be setting my wife's biocube up this weekend using rock that has sat in my sump for the past 6 months. There is 1 piece that was too big/unwieldy for me to get angled into my sump that is dry. I'm planning on doing 50/50 mix of new sand and sand that has sat in my sump with the rock as well.

Think I'll see much of a cycle with this since the majority of the rock and sand has been in my tank already?

You may not see much of a cycle. you may even be ready to go once you do that

That is what I was figuring but wanted to ask. I know the one big piece I wasn't able to fit in will take a bit to build up BB so we're planning on waiting probably a couple weeks before starting with a light cleaning crew.
