I'm
nearing the end of a 500 ml bottle of VDB that was made up in January, and can
report that it contains only a tiny amount of sediment. It's never been
filtered - what's different about it is that weighing and mixing was
interrupted by the call for dinner, at which point the f.a. citrate and
tartaric acid solutions had been combined but the silver not yet added.
This was not done until 2 or 3 hours later.
Can't
promise that others will have the same result, but maybe worth trying if you
have problems with sediment... ?
