Scale Control Filters

The Supercarb candle is now available with a slow-release scale inhibitor that protects heater elements, tanks and pipework from harmful scale buildup. Scale Inhibition filter candles are available as Supercarb SI and Ultracarb SI.  Both long-life filter candles are compatible with the existing range of Doulton slimline filter housings. The Ultracarb SI also removes lead.
