is there a difference? i've been trying to read old threads about putting sand into my tank.

but i've seen pool filter sand called scilica and quarts is it one in the same? is it different? if so what is the difference?
 
Silicon and oxygen, the two most common chemical elements in the Earth's crust, combine as silicon dioxide to form the mineral quartz. [COLOR=blue! important][COLOR=blue! important]Quartz[/color][/color] is the most abundant mineral in the Earth's crust. Quartz has been found in meteorites and in some rocks collected on the moon.
Quartz has the chemical formula SiO2. There are many varieties of quartz, which occurs in nearly all types of igneous, metamorphic and sedimentary rocks. It is an essential mineral in granites, granodiorites and rhyolites. Metamorphism of quartz-bearing igneous and sedimentary rocks typically increases the amount of quartz and its grain size.
Quartz is very resistant to weathering and, therefore, concentrates as sandstones and other detrital rocks. Most sands are weathered fragments of quartz. Sandstone and quartzite are the same materials that are re-lithified (compressed into rock).

one and the same
 
It's been my expierance that sillica sand is much more abrasive. (It's generally used for sandblasting.) My wife and I always use crushed coral in our tanks rather than sand along with a thin layer of decorative rock.

i'm 2 blocks from the beach. and 30 minutes from almost any type of beach sand.

but its my belief that it increases the ph of the tank.

beach sand contains a lot of crushed shells.... will alter ph
