Kirk,
I think the 125 grit sand should work fine. Some folks say that their
builders sand can have some salt in it and they wash it. I tasted mine
(and then spat a lot, no salt though), but just to be on the safe side I
put the mix in pots and run some water through it. If nothing else it
settles the mix. Just be careful the mix doesn't wash out the bottom and
leave a large space, the tray water needs to contact the mix to absorb.
later.
