Ceramic Rings and Biohome Life

[|squee|]

I've been using the same ceramic rings and Biohome Plus for years, since I started this hobby.

I'm wondering, do I need to change them? Or just rinse will do? I've read conflicting reports on the Internet.

Is there such a thing as Biohome/ceramic life limit?

I normally just rinse to clean the dirt and reuse.

Well for reference, they can be used almost forever according to Mr. Chan from NA.
