I am in Homer, AK and the closest place to buy 12.5% liquid chlorine is in Anchorage, 225 miles away. I called APUN yesterday (chemical supplier in Anch.) and he told me that if I brought my own container, which I have from another supplier, the cost to fill it up would be $78.00 for 15 gallons. Actually, driving to Anchorage is no big deal because most people around here do it at least once a month to go to Costco, etc. A 15 gallon container lasts me around 2 months to keep the FC at 3.5 ppm. I'm just wondering if anyone in the lower 48 buys bulk Chlorine this way and how much per gallon?
