Our Own Blend of Tank Treatment We are the only company that has a chemically effective tank treatment that can withstand the heat and humidity of our area. We have worked with a chemical company to formulate a product stronger and more superior than anything you can purchase inside a store or online, for about half the cost to the customer. Our tank treatment comes in 12 month supply and does not require you to measure or even touch the actual chemical, but rather comes in small baggies that require you to "drop and flush" only once a month.
