Spa Boss Filter Free removes rust, scale, oil and fine particles from the filter that back-washing fails to remove. You can tell it is working by the distinct colour changes. For effective cleaning and scale removal, the solution is red; if you have insufficient amount dissolved in the water, the solution will be a yellowed orange.
