To cure or not to Cure is the ?

[howman]

I have a 180g system, 35g fuge, and 90g sump....running with 2 protein skimmers (xtreme 150 and ER CS12-2)

I am thinking of purchasing some new live rock.....75 pounds of tonga slabs.....

My system is mature...running for years.....

Do you think I can just put the new live rock...ordered online...directly into the tank or do i have to cure it first...if yes, for how long?
thanks

I did 25lbs before, just dumped it in the fuge. I never tried 75lbs. I would expect that would be like dumping 10 yellow tangs in your tank at once.

If I were in your shoes, there is no way I would put that much rock in my tank without curring it first. It could wipe out the whole system.
