Adding live rock

[Craigdillman]

I have a 30 gallon tank with about 22ish pounds live rock been up and running few months now got lots of coral and paired clowns in their im looking to add some more live rock but im wondering if that will cause a problem with an already established tank? Would it cause a cycle ? I run a canister filter currently and do weekly water changes

Thoughts?

It depends on whether the live rock you are purchasing is already fully cured or not cured at all. Fully cured live rock can go right into the tank. If it's partially cured or uncured you'll want to cure it in a separate container with a powerhead and heater for a few weeks until all the readings are zero.

I agree with craigdillman post but a rule to remember 1.6 lbs of rock per gallon.
