SCALE BUILD UP IN HOT TUBS
Calcium carbonate deposits create scale build up in hot tubs and have an unattractive rough feel as scale builds up on the hot tub surface. If scale build up in hot tubs is present in the spa circulation system it can cause a reduction in flow and heater efficiency.
Unbalanced water can be due to high pH and/or high total alkalinity. These conditions will create a scale forming tendency. High total alkalinity in particular will make it difficult to adjust the pH and can also be a source of carbonates. Under certain conditions these will deposit on spa surfaces and in the circulation system as calcium carbonate (scale). It is essential that the spa water is tested on a regular basis and the recommended key parameters are maintained. For pH this is 7.2 – 7.6 and total alkalinity is 80 – 150mg/l (ppm). Prompt action may then be taken to make the necessary corrections in order to prevent the water going out of balance.
Actions to be Taken:
To lower the total alkalinity
To lower the pH
To remove scale
Scale on the spa surrounds and surfaces above the water line may be removed with ScaleAway.
1.Shake bottle before use
2.Apply product directly to the spa water whilst the spa pump(s) are turned ‘on’ to aid distribution.
3. Spas treated for heavy scale build-up may require cartridges to be cleaned after treatment.
