CerMedia MarinePureMarine Pure Biofilter Media Gems - 90g, Tan (905002)

Q: How often do they need to be changed?

These types of media don’t need to be changed, there’s bacteria on it that helps lower nitrites and nitrates.

Q: Do these need to be cleaned or changed? Or do I just leave them alone?

As long as you place them after mechanical filtration, they do not need to be cleaned.

Q: Is it safe to put these directly in my tank?

hello yes you can use the Marine pure Gems directly in your tank , if you want to get some help you can add bacteria in liquid directly on your gems to accelerate their growth.
