NO MORE SCALE - NO MORE HARD WATER - USE PURE-STREAM
Hard water is NOT good for your spa or hot tub. Limescale can stick to the spa surface and can block the filters and eventually damage the heater and the pumps.
Using chemicals to counteract this process can be expensive and time consuming but using the Darlly Pure-Stream when filling your spa or pool will remove calcium and magnesium from the water replacing it with soft sodium instead.
Attach garden hose to the filter and fill your spa using a slow to medium flow rate.
The slower the fill the more effective the process.
It is important the filter remains wet so replace the end caps when finished.
One Pure-Stream filter is good for 8000 gallons - around 40 fills for average spa
