Adding live rock to my fug....

I have a 300 gal system that has been up and running for almost 2 years now. I recently made a fug our of an old 75 gal I had and am wanting to add live rock. I have about 300lbs currently in my tank and don't want to have to take any out.....finally got the aquascaping the way I want it.

My question is if I order 25 lbs of live rock rubble can I just throw it in the fuge with as much water and everything as I have or do I still have to wait 3 weeks for the curing process?????

 

you can absolutely add it to the sump, I would not buy "live rock" for this but rather just get dry base rock, in your established system it will become live in very short order!

suggested source for dry rock, I believe if you email him he can make sure the shipment is all rubble, but the bigger pieces will break up easy with a hammer either way.
