Greetings All- While focusing on my 29g tank, I have been slowly establishing my 50g tank. I have about 10lbs of LR, 20lbs of base rock (been in there for about a 10 days), and 20lbs of live sand. The tank has been setup for 6 weeks and the amonia, nitrite, and nitrate are 0, 0, 20 respectively. I will be adding some cured LR in a few days. Will this cause the tank to completely re-cylce or just a mini cycle? Other than the rock/sand, there are no other live creatures in there.
Adding Live Rock to a Cycled Tank, New cycle?

It usually causes a mini cycle if you put in new rock. You shouldn't see a full-blown cycle, but a little ammonia/nitrites should be expected.
If you don't want to have that, you'll need to cure the rock outside of the tank (in a bucket with a powerhead/heater, for example). As you don't have any livestock in that tank, it's not a problem to add rock now, unless you're desperately wanting to stock it soon.

You may not even have a mini cycle if you buy your rock locally and keep it wet during the drive home and put it in the tank immediately. A mini cycle or any for that matter is just the result of die off on the rock during transport.....if you minimize the die off and the rock is fully cured then you may not even see a mini cycle.
not any live stock so nothing to worry about and if its truely cured u should be ok for the most part (problem is its usually not "fully" cured)
