help a 150g newb - let's do this reef together

[jon in alberta]

Hi all,

back from holiday (10 days). I was really excited to see what the live rock I put in my new tank did.

Well here is a close up picture:



as you can see from this close up of a small fragment, there is some algae growing. Also, there is a whole bunch of brown 'film' all over the place.

My plan is to monitor water chem (to see if it has settled down) and maybe introduce a snail or another invertebrate. Suggestions please?
