What is this thing?

Oh yes, the rocks are coming today. Thank you

Are the rocks dry or are they live rock? If dry they are fine to rinse and add, but if not, they may cause an ammonia spike that will kill your coral and fish. How much rock are you getting? I suggest at least 36kg. More if you can afford it.

I am getting 20 kg of live rock for starters. We'll see how we go..
