Sorry it took so long to get back to you. Yes, it makes a huge difference. That rock was uncured which means it had a lot of life on it, and a lot of stuff that died during and after it was shipped. That is both good and bad. Bad in that it will take you longer to cycle, but good in that in the long run, you will have a lot better more diverse system. There will be all kinds of little critters that survived the trip inside the rocks.
Just do like 5 gallons water change every 2 or 3 days for a few weeks until the nitrates come down to atleast 25ppm before adding anything alive. Be sure you have good flow in the tank, and run the lights just like it was full of fish and corals, so that anything left on the rocks will have a better chance of survival. Keep doing regular water changes (5 gallons per week) until you get to under 10ppm nitrates. Under 10 ppm is the ultimate goal. The amonia and nitrite should always stay at 0 ppm. You may see them both come back up and go back to 0 before the cycle is finished, but after everything settles, they will stay at 0.
Basically anything you put in there right now has little chance of survival, so save your money and be patient.
