Prerequisites

Before any search, it is important to validate access to :

• General water supply
• Electricity
• A water drain
• Sufficient space

If you don't have a drain or the space, you can always opt for a CO₂.

Selection criteria

To choose the right size for your salt water softener, it's essential to consider two main factors: the hardness of your water and your daily consumption. Here are the steps to follow:

1. Determine the hardness of your water Water hardness, expressed in French degrees (°f), indicates the concentration of calcium and magnesium ions responsible for limescale. You can obtain this information by consulting your water bill, your water distributor's website or by using a hardness test kit available from Aquacycle.eu.
2. Evaluate your water consumption Estimate the amount of water used by your household over a 10-day period. For example, if your annual consumption is 120 m³, this corresponds to approximately 3.28 m³ over 10 days (120 m³ / 365 days × 10).
3. Calculate softener capacity requirements Multiply your consumption over 10 days by the hardness of your water to obtain the required treatment capacity in °f.m³. For example, with a consumption of 3.28 m³ and a hardness of 35 °f, the calculation would be: 3.28 m³ × 35 °f = 114.8 °f.m³.
4. Determine the volume of resin required The treatment capacity: Knowing that one liter of resin can treat approximately 5 °f.m³ of water, divide the treatment capacity by this value. In our example: 114.8 °f.m³ / 5 °f.m³/L = 22.96 L. It would therefore be wise to opt for a softener with a resin volume of at least 23 liters.

Please note that these calculations may vary according to softener models and technologies. If you have any doubts, don't hesitate to contact us. We're here to help.
