When should I turn on the MH lights?

[Jay180reef]

I've got a new 180gal tank, 130lbs of mostly cured live rock (smells fine, no ammonia), and I've been running the actinics for a couple hours everyday. The first 50lbs has been in the tank about 10 days. Ammonia level is near 0. I just added 80lbs of cured, beautiful Bali rock today(see pictures). It's covered in purple coralline algae, feather dusters and other weird slimy things. Should I do anything special for this live rock? It doesn't fit the description of typical new live rock because (I think) it's fully cured.

Should I turn some more lights on or anything? Any help would be great!

It shouldn't hurt, but the actinics should keep the coraline alive if you want to save electricity, so it won't really help either except for getting the algae growing sooner.

If the bali rock was shipped there will be some die off, though the other 130lbs should tak care of it.

Ya, it was cured once it got here, andi it smelled really nice at the LFS! It kinda reminded me of Cancun.
Thanks grimmjohn

If it's all cured then where's the fish! () : )

Nice looking BB by the way, LOTS of potential, good aquascaping, enjoy your rocks shedding though lol
