I'm not sure if this is the right place for this or not (I'm sorry if it isn't). I just had a 20X40 keyhole shape in ground pool installed. Due to very loose ground and lots of tree roots we had to have 6 yards of concrete poured before they laid the vermiculite base. Now, I have over 10 16lb bags left and the pool store will not take it back and give us credit. Any ideas on how to sell it? I see it on ebay being sold for fertilizer in smaller bags, but that's just too much work. How much does a bag even cost??
Thanks for any help!!
