HTH 3-in-1 water clarifier helps to keep the water of your spa crystal clear by eliminating algae, scale and metal staining from your hot tub. Use it when the water has a dull or slightly cloudy look, but the sanitiser and pH readings are in the correct ranges.

3-in-1 water clarifier is a flocculant: it causes microscopic suspended particles in your spa water to clump together, so that they can be removed more efficiently by your filter.

Water clarifier is only intended to treat mildly cloudy water or dull water. Seriously cloudy water is often a sign of bacteria in your spa. The best approach in this case is to rinse your spa with Spa System Flush and refill it with clean water.
