Gang,

I just called a local pool supply place - he was very familiar with vermiculite as that's what he uses in pool construction.

He told me it's usually fine like sand - but that's not what I've seen in the pictures on the forum???? Hence my confusion/concern.

I am going to order the FB board but would still like to put a small layer 2-3" of vermiculite/concrete down first.

What does everyone think?

Thanks
Dick
