AquaFinesse was born from one Dutchman's refusal to put up with problem hot tub water. Founder Jan de Rijk spent years studying why spa water turns cloudy and smelly, and identified the real culprit: biofilm, the invisible bacterial layer coating pipes and surfaces. His answer was a unique salt-based formula that loosens biofilm so sanitizers can finally do their job. Launched in Europe in 2006 and in the United States in 2011, AquaFinesse quickly won over hot tub owners with its simple weekly treatment routine, noticeably softer-feeling water, and reduced reliance on harsh chemicals. Now owned by water treatment specialist Clearon Corp, AquaFinesse remains a go-to solution for spa owners who want clean, clear, skin-friendly water without the constant chemical juggling.
