Re: [APD] sand



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.

Pool sand is not sea sand IMHO. Sea sand is almost 1/3 shells by my
experience and makes the water very alkaline within a week.
