What Metal Levels Comply With the ACA?

I am trying to make sure that our Bronze Save plan with Aetna does not qualify toward the minimum wage for our medical benefits. If we have a Bronze Save plan with Aetna, is that the same (not necessarily the same plan but same “level” as a Bronze Metal Plan as defined in the federal Affordable Care Act? In order to qualify our medical plan needs to be the equivalent of a “silver” level or higher and right now we have a Bronze, as described by Aetna. Everywhere on the OBAMACARE FACTS’ site to compare plans appears to be for individuals so I want to make sure, for my business.
