I have been mixing in "Pool Sand" from home depot for decades.
It is 100 Percent silica - which is what you are looking for from what you
typed.
Better to go with crushed coral but if it is sand you wan there is your
answer - silica - 50lb bags about 7 bucks at any home depot - it is called
"Pool Sand"

What's that sand you mix with LS? I only need 5# more than what I have.

I also need only 15 lbs. of LR. Anyone know where I can get it?

Thanks.
