Just to share what happens with k1 after 10 years or so. Have 35 liters/ 10 gallons of the kaldness k1 mini -media in an external filter as moving/fluid bed. Had near zero issues with the tank for 12 years; the media was never exposed to medicines or uv light since it’s in my utility space without windows.
I have weighed a small handfull of this brittle mess after drying and there is just very little material left.
I mixed in a newer type of k1 just 2 months ago, that’s the whiter media. Will clean out the old k1 in a few months.
Am not too negative about the stuff, but maybe the info of it deteriorating in this manner, is good to know and worth to share.

After 12 years, I think you got your $$ worth out of that filter media
This is also in a moving bed, so a harsh high contract physical environment. I have mine packed in the canister filter, so I don’t anticipate this kind of physical wear. After 4 years I see no difference other than colour.
