[QUOTE=monkeyfish;1213862]Pool filter sand is good. You will need something to give the plants nutrients though. Many people use mineralized topsoil under the sand. Or you can use root tabs or dose the water column.
My favorite sand is river sand that I get from a local landscaper, 50lb for $3. I just sift the large pebbles out. I started my tank out with Scott's top soil and calcium sulphate and topped the dirt with the river sand.
black diamond sand blasting media works good and is 8 dollars for 50 pounds it can be purchased at any tractor supply company
I think it looks great, and grows plants very well, but it is very sharp particles, able to damage the mouth parts of bottom digging fish like cories. I used to get lots of tiny cuts on my hands while planting in it.
Whatever you do, thoroughly (and i mean thoroughly) rinse that sand to get rid of all the dust. I placed sand in my tank, didn't rinse, constantly have suspended particles which settle on my plants and make them look poor and I have to clean my prefilters every couple of weeks because they are clogged with mud!
I knew I was taking this tank down within 6 months so I didn't bother fixing it.
