I live in SC & have a well for the lawn irrigation system.The water has a lot of iron in it and stains the concrete. Our home owners assoc. requires us to clean the rust. My landscaper has a used Stenner model 85MPHP5 pump and 30 gallon tank he suggests I install to add Rid O'Rust formula 500 to the pumped water to eliminate the rust. Is this the correct usage of these parts, how should I hook them up. Do you have any experience with
eliminating this kind of a problem??
