Our new customer in Hoover Alabama was getting poor results from his garden. He looked to Auburn University for a solution. After having his soil samples analyzed, Auburn told him his garden was suffering from iron poisoning. The well water he was using to water the garden an iron content of over 4 ppm. We installed an Aqua Systems Eradicator AIF automatic backwashing iron filter to solve the problem. It's was the perfect chemical free solution.
