I ordered nearly 250 lbs of of Caribsea Aragonite sand for my builds earlier this summer. I have 3-15lb bags still sitting around that I won't be using anytime soon.
Free to whoever wants to come by and grab them -- take all 3 (maybe 4 bags - I didn't open 1 box).
Located in Castro Valley near the Trader Joes
This link has a picture of the bags for reference -- doesn't look like Petco has it anymore so I can't link to the exact bags I purchased: https://bigbluereefaquatics.com/products/carribsea-aragonite-sand
