Chlorine dosing to manage bacterial iron on a bore

Many growers are challenged by the buildup of brown sludge in irrigation systems caused by iron bacteria. Ben Funnekotter at The Seedling Factory showed us how he controls iron bacteria in his contaminated bores during a recent tour of his operations. His home-made system provides continual chlorine treatment to the bore (which kills the bacteria) using a simple Venturi setup that draws water through a canister containing chlorine tablets.
