Re: [APD] sand



Really? Sand is primarily silicon dioxide, or SiO2, usually in the form of
quartz, which is inert and most assuredly not soluble in water. Shells and
other materials from animal decomposition are not, by definition sand,
although they are often constituents of same.

Since when?

Sand is mostly calcium carbonate, ie the dead shells of invertebrate 
animals. Course it dissolves in water! It is what gives water GH and KH. :)
