How do you know a tank has cycled?

[FaRico]

I inherited a 50 gal FOWLR tank, and had it running for 6 months successfully, until the summer sun started shining on it all day. I have now upgraded to a 100 gal with sump. To get to my point, how do I know when it has cycled? Someone once told me that the water gets cloudy, but I had not noticed that in my previous tank.

Best thing to do is bring a sample of water to ....well.....us at RC and have us test it for Ammonia, nitrite and nitrate....or you can get the test kits to do it yourself.

I will do this publicly here. to canreef....the world of the salt addicted and thus, lightly walleted.

Simply put, the cycle is over when ammonia and nitrite are both zero. Read the link in my signature about cycling for some info.
