I'm planning on adding more LR to my existing 40# of rock I have in my 37G tank. The tank is fairly deep so I want to scape it as high as possible to keep SPS and any high light demanding corals.

My tank is pretty stable right now all fish and corals doing very well in their current stage. How should I add the new LR (thats supposedly cured from the LFS) to my new tank?

Second, I plan on getting some LR Rubble for my sump - will this cause a ammonia spike or any chaose to my tank?

Best to buy it and cure it yourself at home and then add it to your tank..both the LR for your display and the rubble.

LFS's fequently add newer rock to their selling tanks, so there is no guarantee that it is fully cured.
In this way, you will be sure and can also check the rock for pests first. :)

Cure it in the water removed during your water changes.

Will I need to have lighting for the rocks? I plan on keeping the rocks in a sep tank with a PH to keep the water ciruclating. Can any light do?

what happens when you add live rock that is not cured to your tank? Just wondering because i just did it.
depends on your tank setup, if you already have a whole lot of established rock, that seriously outweighs the amount of rock you just put in then pretty much a mini cycle will happen but will clear up very quickly. But if its not that case then you probably just set off another full cycle of your tank.

Or do you mean uncured as in straight from the ocean, or some other source? If thats the case then you may have also just introduced some unwanted pests into your tank. Gorilla crabs, aptaisia, etc.

I've added new pieces of LR ("uncured") to my tank after I set it up, and I have never had any problems. I think as long as your tank is stable and the amount of cured rock outweight the amount that you are adding, it should be fine.

Yeah 10 lbs added to 75 is still a decent percentage (13 1/3%), but it shouldn't really affect it too much. But it's not like what I was talking about, like adding 50 lbs to a 75 established lbs.

I picked up some rock on my last vacation in the Bahamas. I was hesitant, but couldn't help myself and threw in a few pieces at a time. Wouldn't recommend it, but I didn't really have any problems.
