Probabaly not safe to use unless you are in need of really hard water. A lot of that is greek to me too (I assume you tried to parse the Wikipedia Entry), but Alkali Feldspar is going to leech Calcium into your water, raising the hardness and PH. Now, if you're doing livebearers or Rift Lake or Central American cichlids or brackish water fish or desert gobies, you'll be fine. If you're doing anything like Cories or Loaches or Pleco or Tetras or Anabantids, or anything that likes soft, acid water, not so fine.

It will probably overwhelm any amount of driftwood you could use. Your best bet is to stick with hardwater fish. What size tank do you have?

If that's a 33 long, that could be an awesome tank with lake Tanganyika shell dwellers. Otherwise, you could do a really neat North or Central American tank. A male and 4 female sailfin mollies, a firemouth or 2, and an American-Flag Fish or two. You could plant that second option with Vals and Java moss and java fern and hormwort - all do great in hard water. So does Mexican Oakleaf.

Your best bet is really to find fish that work with the conditions you're setting up.

Adult size is up to 6" for some species of Male Sailfin Molly (I think it's P. velifera that gets big) - More likely 4" (what you'll see in pet stores is a hybrid of P. latipinna and others). If you get a male and a harem for him, they will fill a tank of any size you care to name, given time and places for the fry to get out of the way. 10 gallons is too small for anything but a temporary breeding or grow out tank.

Still, if you want to use that sand, hard water fish remain your best choice. Someone else can tell you about rift lake cichlids. They might be the way to go for you.

For a ten gallons, you may want 4 American flag fish or a harem of Neolamprologus ocellaris.:) So what fish have you decide?

I'm ready for the pressure.
The drama and the pleasure!
If there is one thing I want to see here, it's HUMOR.
I believe I can fly!
I believe I can touch the sky!
I think about it every night and day!
I stand in awe of my body.
