Description
Blue Horizons Calcium Hardness – 25 kg Bucket
Blue Horizons Calcium Hardness – Calcium hardness (or total hardness) is the measure of how hard or soft the water is. Use these granules to increase your levels.
The level will vary depending on where your water supply comes from, for example in some parts of Scotland the water is very soft and in parts of Kent 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.
If the calcium hardness of your pool water is less than 200mg/l then it should be increased using Blue Horizons Calcium Hardness Raiser, details of dose rates can be found below:
