what is all this on my rock???

here is a video of my tank
i had to make a video as i couldnt get a good enough pic.

at 0:59 on the video there is some green stuff on the rock and also some other stuff.can anyone tell me what they are?

YouTube - my new 40 gallon saltwater tank setup day 20

 

looks like some corraline algae...it will be all over the place once the tank is about a year old or so...it doesnt appear to be "flowing" like cyano...but if it is "flowing" than its probably cyano...it appears the tank is fairly new so a few water changes should take care of it... but dont over feed cuz it will get worse

 

Water!! LOL.... ;D Just teasing.. I'd say coralline algae as well...

 

Touch it. If it wipes off it's cyano. If you can't srape it with your fingernail it's coralline. I only saw what appears to be red coralline growing tho.

 

whats the green stuff?

 

I honestly couldn't see the "green stuff" but if you do the same 'test' with your finger nail that'd be coralline as well. CA grows in many colors..purple's, pinks, greens to name a few.

 

Yep i've even gotten yellow and orangeish before
