Oh these are all very doable.
I'll get on it after a nap. I've got a bad cold. But I'm excited, I love id'ing macro algae. 
I've only ever used sand. I have live sand in my picos & 4" of oolite in my biotope. People have mixed feelings about the live sand, but I must have gotten a fresh batch because my picos are really doing well.
time for a nap!

iv took loads out of the tank, some of it grows really fast. iv read somewhere that a lot of the oceans sand comes from the hard algaes.
