what's on my LR?

[ivy2dw7]

I bought 2 pieces of uncured live rock to cylce my tank a week ago and I scrubbed off what looked like dead spots and left the "live" spots alone. Now the live spots are starting to grow, one looks like and orange spongey material, looks like i have some brownish branch starting to grow in 2 places and there even seems to be a beige-white polyp in one spot. Is this coral growing on my live rock??

Oh and one other question. I only have 3 pieces of LR in my tank right now, I am definitely wanting to add a lot more, it's close to 20 pounds right now, I'd like probably 35-40 (37g tank, 21" high). It is safe to stack live rock? Because I'd like to build it up in the back so that it's pretty high.

It probably is a sponge. I had one on my Fiji Premium Rock that died.
Yes, you can stack the rock, just make sure it isnt wobbly. They make an epoxy that you can buy that you can glue them together

So that means the other things I'm seeing on the rock are probably coral? Free coral, cool...

Maybe it'll grow a little more so I can figure out what it all is.

It is likely coral. Thats the fun part about LR. Unfortunately, unless you have good enough lighting it won't grow.
