I have 3 unopened bags Bahama Oolite for anyone that needs it. It's a pretty fine grade so keep that in mind. Also, I have around 100lbs of CaribSea Fiji Pink that I pulled out of my system. It's a much nicer grade...not too big not too small. It's currently sitting in two 5 gallon buckets. I think I had it in the system for around 3.5 months so it's not all dookie brown in color. It still emits a bit of a white cloud so a quick rinse is recommended. All I ask is that you bring an "aquarium use" bucket with a lid to do the swap if you want the entire bucket.
