Oh! Well, all bets are off.
Zep put the word "fresh" only down at the end of the post; my Sov is about the same age as his, and the black tank looks a lot like his fresh tank, however the ridge down the middle should have twigged me to the fact that it's the fresh tank.
No Geo plan for the fresh tank, IIRC. Even ice would be awkward to get in there.
