Having just shut down my pond, I have six 15 gallon bags of K2 for sale. [Actually, used a 5.5 gallon bucket x3 so probably more than 15 gallons in each bag]. Looking to get $100.00 a bag. I'll have general shipping costs, to be paid by buyer, in a couple days...using UPS ground. email me at gfwachter1@gmail.com if interested...Rochester, NY
