I probably will now, I just really liked the color or my sand outside. I have some questions about PFS also. How fine is it? I don't want it to get in my filter when stirred. Is it that white? I was hoping for more of a light grey color for my sand.Don't knock yourself out man. PFS is cheap, readily available, and tested and proven by MANY MFK'ers before you. Why not just use that?
I decided against it because I was smelling chlorine while washing the sand.The only two issues with using sand outside your apartment:
1) It's much more likely to contain lethal chemicals than purchased at the store. Pesticides, oil, other undesirable items (scraps of metal, shards of glass, etc.) could be in any batch you select.
2) Unless the owner has authorized taking it, it's considered to be a form of petit larceny. I would certainly ask the owner before taking it.
Otherwise, I don't see an issue.
Hello; The chlorine smell is likely from the local water source and not the sand. Not a problem. I recently washed a couple hunfred pounds of gravel and soaked it in a clorox solution. I gave it a final rinse and also allowed the tank to sit with the gravel and full of water for a few of days with a bubbler before adding plants and later fish.I decided against it because I was smelling chlorine while washing the sand.
It should also be noted that you need to use caution when sieving dry silica sand, as the dust is like airborne shards of glass, which can cause severe respiratory damage if inhaled.I have used construction sand which is cheap. I use a colander of make a screen to sift out the very fine dust while it is dry.
