New cycle, white film?

[captmilkchoco]

Hi everyone! Just started cycling a 29-gal BioCube. Following Sk8r's advice here.

So I've been putting in a couple pinches of fish food pellets every day. After about 4 days now, there seems to be a white film growing over the inert pellets in the sand. I was just wondering if this was anything I should worry about or just part of the cycle and bacteria growing. Any help would be appreciated. Thanks!

(Started with mostly dry conditioned rock, ~5 pounds of live rock, 30 lbs of live sand)

It is most likely bacteria, nothing to worry about.

It kind of looks like it's growing on my rocks too...Pictures here. Just a little paranoid, so I hope it's all just part of the nitrifying bacteria growth.
