Description

This listing covers the 1Kg size.

Discover Deep Blue Pro Calcium Hardness Plus, a straightforward answer to keeping your spa water properly balanced for calcium hardness. If getting the hardness level right has been a challenge, Deep Blue Pro Hardness Plus takes the guesswork out of the process.

Calcium hardness, sometimes called total hardness, is one of the key factors behind good spa water quality. It reflects how hard or soft your water is, shaped by the mineral salts, mostly calcium, that are dissolved within it. Because water hardness depends on where your supply comes from, levels can differ considerably from one region to another.

Getting calcium hardness right matters, since an imbalance can bring a range of problems. Water that is too soft can turn corrosive, etch surfaces and cause foaming, whilst water that is too hard can lead to scale, filter calcification, cloudiness and staining, any of which can spoil your enjoyment of the spa.

Deep Blue Pro Calcium Hardness Plus solves this with clear dosage guidance for whatever level of adjustment you need, whether you’re nudging the hardness up in small steps or holding it steady within the ideal range, this product makes the job simple and reliable.

As an example, raising the hardness in 1,000 litres by 10mg/l calls for 15g of Hardness Plus, while a bigger adjustment of 50mg/l calls for 76g. Guidance this clear means you can tailor the treatment precisely to your spa’s needs.

Where your spa water’s calcium hardness climbs above 200mg/l, Deep Blue Pro ScaleAway takes over, helping to stop scale forming within the filter, heater, pipework and spa surfaces. This companion product keeps your spa protected from scale even when hardness runs high.

When hardness needs bringing down, Deep Blue Pro ScaleAway provides an easy answer. Just 25ml of ScaleAway treats 1,000 litres, making it simple to guide your water back towards the ideal hardness range. Applied regularly at the recommended intervals, it brings hardness gradually back to where it should be.

Choosing Deep Blue Pro Calcium Hardness Plus alongside ScaleAway means investing in more than water treatment, it means investing in your spa’s long-term performance and lifespan. Leave hardness worries behind and enjoy consistently balanced, crystal-clear water that lifts your spa experience.

See what a difference careful water treatment makes and get the most from your spa with Deep Blue Pro’s range of solutions. Rely on a brand built around quality, performance and customer care, so your spa water stays inviting and pristine every time you use it.

Discover the Deep Blue Pro range and set a new benchmark for spa water care. Your path to properly balanced water begins here. Step into a refreshed spa experience, backed by the knowledge and dependability behind Deep Blue Pro.

Manufacturers description:

Deep Blue Pro Calcium Hardness Plus – If the calcium hardness of your spa water is less than 100mg/l then it should be increased using Deep Blue Pro 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 Deep Blue Pro 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 Deep Blue Pro 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.
