Aeration does not work for chloramine, however, which is a less volatile additive used by some municipal water authorities. You’ll need to add a dechlorination agent as well.
The water will be ready for immediate use. If you’re using the water in a fish tank with a biological filter, choose a dechlorination agent that doesn’t have an ammonia remover, which could cause problems in your filter. [2] X Research source
Buy the appropriate pump for your tank’s size and type, and the pets you’ll be keeping in the tank.
Activated carbon filters remove both chlorine and chloramine. [4] X Research source Choose an activated carbon filter that has been certified by NSF International, a nonprofit that tests and certifies water filtration products.
Additionally, reverse osmosis filters are energy-intensive and produce large volumes of wastewater.
Boiling for at least 20 minutes will also remove chloramine, which is added instead of chlorine in some areas.
The precise length of time needed to dechlorinate water using this method depends on the volume of chlorine you’re attempting to remove and the amount of direct sunlight the water receives. Also, the wider and shallower the container, the faster the process will occur. Check the water regularly using a chlorine test kit to determine how much chlorine remains in the water. Evaporation won’t remove chloramine, which is used instead of chlorine in some water supplies. It’s also not recommended for drinking water since contamination can easily occur.
Ascorbic acid is affordable and can be obtained from most pet stores. Ascorbic acid removes both chlorine and chloramine. It also shouldn’t noticeably affect the flavor of the water, if you choose to use this method for drinking water.
Typically, you should treat chlorinated water using a UV light at the 254 nanometer wavelength that has a radiant energy density of 600 milliliters (20. 3 fl oz) per 1 square centimetre (0. 16 sq in). UV light will remove chloramine as well as chlorine. This is also a suitable dechlorination process for drinking water.
