The Purestream+ is designed to reduce water hardness in your hot tub, which can help lower maintenance costs in areas with hard water. Hard water causes uncomfortable scaling on the walls, white calcium deposits on your jets, and buildup in the filter. Limescale can also build up inside the heater, causing unseen damage. Over time, this can lead to calcium flakes appearing in your hot tub. The PureStream + is designed as a one or two use disposable product dependant on hot tub size and local water hardness.
 
Directions 
Simply attach your garden hose to the filter and fill your hot tub using a slow/medium flow rate – the slower the fill the more effective the process.
 
Suitability / Application
The PureStream+ is suitable for complete fill of an average-size 4-6 seat hot tub with a 1200 litre fill capacity. The PureStream+ is designed as a one or two use disposable product.
 
Performance will depend on local water hardness and volume of water required to fill the hot tub.
