Help me to identify!

[sanechka2005]

Hello, everybody,

My tank is 2 weeks old, I got plenty of life rocks and my cycle just finished. Please, help me to identify some items...

the first one: this something is growing on my rocks. I dont know what is it. I didnt have it for sure when I brought rocks at home:

What are those white spots? they are everywhere....

I have several of these "hats" in my tank. They were on the rocks from the beginning:

I just noticed this hairy thing recently, i am not sure if it was on the rock from the beginning or just grow

Thank you!
Alexandra

the hats are some bleached encrusting coral.. i dont know the exact name for it but i collected some some rocks with that coral all over it when i was out in the keys but when i got it back to my tank it didnt last too long.. the other id's need bigger and better pictures, i suggest shutting off the pumps and powerheads and bring it to the front of the tank or out of the tank if there is no coral on the rock yet..

What is the origin of your rock, my friend?
