HD Video of My Tank: Help Me ID Please!!!

[gcgrad]

Here is my aquarium at 2.5 months old. I need help identifying a few things if you don't mind. I have my own theory for what most of it is but don't want to say so I don't perhaps influence the replies. Main things I looking for IDs is the growth on the sand bed, the hair looking stuff on the sand bed, the bright green bubble looking growth on the rock, and the small pink coral colony on the purple piece of live rock. Thanks for your responses!

The video was shot and edited by my brother-in-law. He literally put this together in 20 minutes. He has a broadcast video production company in Atlanta. PM me if your interested.

all your powerheads are pointing up. There seems to be little to no flow down by your rocks. cyano is going to grow where there is no flow and excess nutrients. point your powerheads toward the rock.

+1. I would also say add more flow as well as giving more flow to the bottom of the tank. Get a couple of MP40's if you can afford it. Those koralias are not cutting it I think. Especially for the length of your tank.
