Live rock question

[richardhmc]

Does live rock need lighting to be "alive"? to be beneficial to the tank biologically?

 

[prattreef]

No, as the majority of the benefit is bacterial. However, you will lose some of the life that is on the rock that is light dependent.

Okay great! because I moved a lot of rocks that I don't like from my tank to my sump where there is light only in the refuge

You may cause a mini cycle as there will be some die off from the light dependent life.

Unless he moved a lot of rock and it was loaded with macroalgae etc. I find this highly unlikely.

 

[Imbarrie]

Well he did say he moved a lot of rock.

any large movement of rocks may cause a spike but not enough to kill anything as long as the rocks r cured.

I moved about say 10 lbs of rock out the 60 I have.
