So you think I can contact Tunze in Germany directly and ask for an exchange housing?
The unit is tight now with my gluing👍
As I wrote I used diluted acetic acid not muriatic, and I only used it on the pump and rotator.

I see the point of using cleaner medias, so will use it from now on, but there were no visible residues I could see of the ARM media
