Live Rock Experts - How to deal with new live rock

[bassman]

I recently purchased 45lbs of live rock from a forum member with two very established tanks. One tank had a fair bit of red hair algae in it, the other had lots of coraline, a little bubble algae and no red hair. 90% of the rock I took was from is tank.

I currently have 75 lbs of LR in my display tank so I only put two peices in. Both with lots of coraline and I removed all the bubble algae I could see.

The rest of the rock is currently in my 20 gallon refugium under two 17-watt GE energy saver, natural day light, 6700K lights. I cleaned off most of the bubble algae but other then that I didn't do anything to the rock.
I was out of water, in a rubbermaid for 2 hrs tops, still wet when it came out.

I ended up having to put one large rock in my sump, with no lights what so ever. This piece has some red hair algae on it.

Should I be concerned about at ton of die off? I am expecting some die off as he was running 250 watt halides, I only run 150's on my main tank and next to nothing on my fuge when compared to 250 watts of halides.
I am curious as to how fast any die off will happen, or if it will be a slow gradual process.

My main DT tank is 55 gal, the sump is over 80 and the fuge is 20, so approx. 150 gallons total water.

I am thinking of possibly upgrading my refugium lighting to higher wattage bulbs (65w) but the same kelvin rating as to promote macro aglae growth.

I am wondering if I should pull all the new rock out this weekend and cook / refresh it in rubbermaids for a couple of months. I could use the dump water from my main tanks water changes to clean and refresh the water the rocks are in every 2 weeks.

Or will it be just fine the way it is?
