Live rock question

[Ronald Marcelo]

co worker just gave me about 7 pounds of live rock with coralline growth on it! He's the man LOL. Feeling really lucky

Should I have any concerns putting this rock straight into my tank? It came from a fully established tank going on about 3-4 years now. Thanks in advance.

I believe 24 hours is the max for live rock to not be submerged. I may be wrong but how big is your tank? 7 lbs may not be enough to do anything anyway depending on tank size

Oh no im sorry i have 45lbs in my tank already. I currently have zero in my refugium so i wanted to add a few pieces in there and another piece to my main. I believe it is 24hrs but i just wanted to know if i could cause a mini cycle in anyway... The rock is cured. Thanks again... I was just wondering whats the worst case scenario
