Went to the local stone supplier, they recommended qp as opposed to stone dust (screenings) since I will be compacting about 4" or so.

I'll probably relpace my liner since Im worried about it shrinking. Does anyone have any tips on getting a smooth bottom... Ive seen the tips on styro soles ect but was wondering if I should try to give the sand base a "broom" finish after compacting like they do w/concrete and let the weight of the water do the rest. Ive seen the rounded trowels but am hesitant since I am terrible at drywall compond.

Thanks Again
