Many water municipalities add calcium carbonate to the water supply to prevent corrosion in the pipes. This will make the water basic or a high pH. Not only will excess minerals build up as salts in the system but also high pH will prevent nutrients from being absorbed by the roots. Therefore it is important to filter water that is used to irrigate living walls.
