So, I'm not happy with my aquascaping. I have around 15-20 corals and according to BRS about half the rock I should have in a 350 gallon display. I'm going for a minimalist look, but plenty of area to put corals and allow things to grow in.

My tank is 6 months old with, well, 5 fish now... (long story). and am ordering some stax rocks (cut rock to allow stacking) as I want to add some height to my rock work. I've got a 31" tall tank and would like the rocks to go above 15"... I just ordered 40 pounds of staxx cut dry rock. I've also got another 25-40 lbs of smaller pieces of Rock work dried for a few years now that I had in a previous tank.

So, I'm hoping to add around 50 - 75 lbs of rock in the form of some taller superstructures. Adding at least one if not multiple towers around 20-25" tall. And redoing my base rock a little.

I also have around 2-3 inch sand bed. My question to the internets is a lot of dry rock says to cycle it prior to adding to an established system. Why is this? Other than color and algae growth on the rock, why does it matter? Does it generate a new cycle of some type? I can't imagine with all the filtration I have on the tank, that a new ammonia spike would occur? And the shear amount of water volume?
 
Some of the dry rock is known to leach certain elements into the water (ex phosphates), so that is why there is recommendation to cure it 1st before putting it in the tank. Man made rock can also affect pH as well, so curing outside of DT will prevent pH to spike.
