Description
Introducing Relax Calcium Hardness Plus, the essential solution for maintaining the optimal calcium hardness levels in your spa water. If your spa’s calcium hardness falls below 100mg/l, it’s crucial to boost it using Relax Hardness Plus to ensure a balanced and healthy water environment for your relaxation and enjoyment.
Calcium hardness, also known as total hardness, plays a significant role in determining the hardness or softness of your water. The levels can vary based on your water source, with regions like Scotland and South Wales often having very soft water, while areas like the South East may have harder water due to higher mineral salt content, primarily calcium. The more mineral salts present, the harder the water becomes, impacting the overall water quality.
Incorrect calcium hardness levels can lead to a range of issues that affect both your spa equipment and your overall enjoyment of the water. Low hardness levels can result in corrosive water, surface etching, foam formation, while high hardness levels may cause scale build-up, filter calcification, cloudy water, and unsightly staining. Maintaining the ideal calcium hardness range is essential for the longevity of your spa and your comfort.
For optimal performance, it is recommended to keep the calcium hardness below 100mg/l for low levels and above 200mg/l for high levels. If your spa water falls below the recommended range, using Relax Hardness Plus can help you achieve the desired balance efficiently, ensuring a safe and enjoyable spa experience.
When it comes to dosing, the application of Relax Hardness Plus is straightforward and effective. To increase the hardness by 10mg/l in 1,000 litres of water, simply add 15g of Hardness Plus. For a 25mg/l increase, use 38g, and for a 50mg/l boost, 76g of Hardness Plus is recommended. These precise dose rates make it easy to adjust the calcium hardness levels according to your specific requirements, maintaining water quality with precision.
If your spa water’s calcium hardness surpasses 200mg/l, indicating high levels that can lead to scale deposits in your spa system, it is advised to use Relax ScaleAway to prevent such issues. Scale deposits can clog filters, damage the heater, affect pipework, and mar the appearance of spa surfaces. Relax ScaleAway offers a proactive solution to combat scale formation, safeguarding your spa investment and ensuring continued performance.
For reducing hardness levels in your spa water, the recommended dose of ScaleAway is 25ml per 1,000 litres. Repeat this dosage every 24 hours until your calcium hardness levels return to the normal range, maintaining a balanced water environment within your spa system.
Invest in Relax Calcium Hardness Plus and Relax ScaleAway to effectively manage your spa water’s calcium hardness levels, ensuring optimal performance, longevity, and water quality. Trust in these reliable solutions to enjoy a hassle-free spa experience, free from common issues associated with incorrect calcium hardness levels.
Manufacturers description:
Relax Calcium Hardness Plus – If the calcium hardness of your spa water is less than 100mg/l then it should be increased using Relax Hardness Plus.
Calcium Hardness:Calcium hardness (or total hardness) is the measure of how hard or soft the water is. The level will vary depending on where your water supply comes from, for example in some parts of Scotland & South Wales the water is very soft and in the South East the water can be very hard. The hardness depends upon the amount of mineral salts (mainly calcium) that are dissolved in the water and the more salts there are the harder the water is.
Problems Associated with incorrect Calcium Hardness Levels:
Low Hardness – Corrosive water
Low Hardness – Etching of surfaces
Low Hardness – Foam
High Hardness – Scale formation
High Hardness – Filter calcification
High Hardness – Cloudy water
High Hardness – Staining
Ideal Ranges:Low calcium Hardness less than 100mg/l
High calcium Hardness more than 200mg/l
If the calcium hardness of your spa water is less than 100mg/l then it should be increased using Relax Hardness Plus.
Dose Rates:To Increase Hardness in 1,000 Litres by 10mg/l requires 15g of Hardness Plus
To Increase Hardness in 1,000 Litres by 25mg/l requires 38g of Hardness Plus
To Increase Hardness in 1,000 Litres by 50mg/l requires 76g of Hardness Plus
If the calcium hardness of your spa water is greater than 200mg/l then Relax ScaleAway should be used to help prevent scale deposits within the filter, heater, pipework and on spa surfaces.
Dose Rates:To reduce hardness in 1,000 Litres requires 25ml of ScaleAway – Repeat every 24 hours untill your levels have returned back to normal range.
