How to sterilize bio filter media

[ReefBeta]

I'm running a quarantine using bio media (biomax) that was seeded from my main tank. After it's done, I need to sterilize it before putting back to main tank for seeding for next time, right?


So how do I sterilize bio media? Bleach soak it?

Bleach and set it In the sun. I use diluted bleach.
