Description
Welcome to the world of Deep Blue Pro 6 x 1kg Spa Hardness Plus, your go-to solution for maintaining optimal calcium hardness levels in your spa water. If you’ve been struggling with achieving the perfect balance in your spa, fret not, as Deep Blue Pro is here to rescue your water quality.
Calcium hardness, also referred to as total hardness, is a critical factor in determining the overall quality of your spa water. It signifies the hardness or softness of the water, influenced by mineral salts, predominantly calcium, dissolved in the water. The hardness of water can vary based on the source, with different regions exhibiting distinct levels of hardness due to the mineral content in the water.
Maintaining the correct calcium hardness levels is essential to avoid a range of potential issues associated with imbalanced water conditions. Low hardness levels can lead to corrosive water, surface etching, and foam formation, while high hardness can result in scale formation, filter calcification, cloudy water, and staining, all of which can compromise the quality of your spa experience.
With Deep Blue Pro 6 x 1kg Spa Hardness Plus, you have a precise solution at your fingertips. This product offers clear dosage recommendations tailored to address varying hardness levels. Whether you need to incrementally increase hardness or maintain it within the ideal range, Deep Blue Pro Hardness Plus provides a straightforward and effective way to achieve the desired balance.
For example, if you need to raise the hardness by 10mg/l in 1,000 litres of water, you would require 15g of Hardness Plus. For a more significant adjustment, such as increasing the hardness by 50mg/l, 76g of Hardness Plus should be added. These dosage guidelines simplify the customization of treatment based on your spa’s specific requirements.
In instances where the calcium hardness exceeds 200mg/l, Deep Blue Pro ScaleAway steps in to prevent scale deposits within various spa components, including filters, heaters, pipework, and surfaces. This additional product ensures that even in high-hardness scenarios, your spa remains free from the adverse effects of scale buildup.
If hardness reduction is necessary, Deep Blue Pro ScaleAway offers a user-friendly solution. With just 25ml of ScaleAway required to reduce hardness in 1,000 litres of water, this product streamlines the process of restoring your water to the optimal hardness levels. Regular application at recommended intervals facilitates a gradual return to the desired hardness range.
By opting for Deep Blue Pro 6 x 1kg Spa Hardness Plus and ScaleAway, you’re not merely purchasing water treatment products; you’re investing in the longevity and efficiency of your spa. Bid farewell to concerns about incorrect hardness levels and welcome a world of balanced, crystal-clear water that elevates your spa experience to new heights.
Experience the transformative impact of precise water treatment and unlock the full potential of your spa with Deep Blue Pro’s innovative solutions. Trust in a brand that prioritizes quality, efficacy, and customer satisfaction, ensuring that your spa water remains pristine and inviting every time you indulge in a relaxing soak.
Embrace the power of Deep Blue Pro products and embrace a new standard in spa water maintenance. Your journey toward perfectly balanced water commences here. Dive into a revitalized spa experience, supported by the expertise and dependability of Deep Blue Pro’s offerings.
Manufacturer’s Description:

Calcium Hardness: Calcium hardness, or total hardness, indicates the hardness or softness of water. The level varies depending on the water source; for example, water from different regions may exhibit varying levels of hardness due to mineral salts, primarily calcium, in the water.
