How do I know if my tank is done cycling?

[Maxx Yung]

I just got the Red Sea Reefer 750XXL 3 days ago (hype hype hype). I have a protein skimmer Curve 7, filter socks, and about 150lbs of live rock and probably more sand. People have said that a cycle will be done if you test the ammonia and nitrites are 0.

My question is, because of all that live bacteria from the rocks and sand, and adding IO's Bio Spira and Dr.Tim's One and Only, wouldn't the cycle be significantly faster. (Talking about 2 weeks or less)

possibly. get a seachem ammonia badge as it tests for free ammonia and is very accurate. does pure ammonia to 2ppm. when it drops to 0 within 8-12 hours you’re cycle. if you used live rock then you may not even see a cycle at all!
