I was always under the impression that aragonite DSBs deteriorate at approx the rate of 1/4" to 1/2" anually. If this sand is replaced anually refreshing the DSB
, there seems to me, no problem at all. A deeper DSB
in a fuge sounds very logical as well. As for silica sand, I shrug. However the occasional sand swap without going to deep under the surface as Mr. McAllen has pointed out sounds logical as well. In my very limited research and knowledge I will make a prediction just as "those other guys" have. (I am very loyal to my friends here at AA!):
-The plenium will retire to the clearance rack just as the UGF
and the tapered leg levis.
LONG LIVE THE DSB
-thanks for allowing me to throw my opinions and theories out.
