    Jcal if you still looking for some silica sand products. I found an old survey of mines on the east coast, might be able to see if the ones near you sell it still. The silica sand company I mentioned before has been operating since that survey was done on the mines.

    Can't seem to find anything on the sewanee silica sand conglomerate. I'm looking around to see what might be marketed as retail.

    This sand looks like the aquarium gravel I used to use when in High School in the late 1960's. At the time it was called "#3 quartz". It was the standard aquarium gravel. $0.05 per lb. Now there are many high tech substrates sold by various companies for aquatic gardening.

    Try searching for filter sands. It does come in various grades. Almost all are quartz/silica so they don't dissolve over time. I use a coarser sand/gravel at the bottom of Ion Exchange cylinders to enable better water distribution.

    Thank you Jerry. Didn't think of that but makes sense. I'll give it a search

    Jcal, also see if there are any "Well construction" companies around. They use industrial silica for well lining as I mentioned in the reply to your original question. The sand I am using is not aquarium gravel as it is too sharp. The particles are about 2-3mm in diameter.

    I measured some aquarium gravel of the 1960's vintage and I'd have to say the #3 is referring to 3 mm max size of the grain. Minimum would be around 1.5 mm.
