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.
