Every aquarist who does regular partial water changes (and we all should) is faced with the question of how best to condition water for aquarium use.
Many aquarists simply add a dechlorinating agent to their tap water, then allow it to sit for a while before use. Others have other methods.
“In [our water storage container] we keep a bag of boiled peat and a Tetra pond filter,” report Al and Lana Anderson. “We add two handfuls of salt per 50 gallons of water and this system works fine for us. For Nothos we use water from our well, that has been seasoned in our African system.” “I have a reservoir (a 20 gallon plastic drum) that I fill with a hose from the faucet, add salt and dechlorinate, aerate overnight and then siphon down to the tanks,” says Lee Harper.
