;it would be a fortune in sand. also, it would be extremely hard to keep it

:sand bed, how do you propose filtering that water?
I would imagine sand to be one of the cheapest bulk material I can
buy. I figure all I should be paying for is the handling and storage,
which should be low if bought by truck loads. As for sand getting into
water filtration system, if sand is found sitting on the bottom of a
flowing stream, I figure most of it should pretty much stay put at the
bottom of a stagnant pool. I am more concerned about how to keep
nasties from growing in the sand, and whether there will be problem
cleaning leaves out from the bottom of the pool. Wouldn't swimming
pool chlorine diffuse into the the sand for as far as it matters?
