I am moving from gravel to sand, I went with Plain Petco Brand Blue, My hubby picked the color. I am going to be getting Cories, don't know which ones yet. perhaps a few peppered, bronze or albino. Depends on which one hubby likes. 
My question, I know you need to aerate the sand, will the Cories do the job alone or do I need to find MTS, or shift the sand myself? I want a happy healthy tank.
Any advice would be appreciated.
