FYI,  We have recently we've been told that Allied Universal located in Brunswick, Ga will set you up with a chlorine tank and holding tank basically free of charge if you use 500 gallons or more monthly. They will also deliver. We are in the process of working with them to see if we can have a tank installed at our shop. Of course we will have to gain city approval which I'm told is very easyas long as you have it fenced in and a catch tank should a leak develop. We will keep you posted as we find out more. I'm sure we will see a tremendous savings. We currently are paying 90 cents a gallon and using somewhere in the neighborhood of 800 plus gallons per month. Sure would be nice to have it readily available. We currently have two 220 gallon tanks mounted on a trailor and fill those at a local pool supply store to keep on premises. This would eliminate the time it takes to go and fill the tanks and transport it back to our shop. Anything to reduce daily operating expenses.....

I called Don at Brainerd and he hooked me up with everything at these prices plus shipping
