looks like a new setup :). Don't worry about these things they will self-regulate eventually. Do you have LR with coralline algae? If not I would get one and scrape it under power head to activate CA growth.

What does scraping in front of a powerhead do?

Spreads the spores.

I have 16lbs of live and 40 lbs of dead rock. The live rock is purple, I think that means shell coralline, as for getting the spores for coralline I found some small rocks covered in it at jacks and they gave me a couple rocks that I placed around my tank. Although I'm currently fighting a valient battle with what I think is cyano.
