Hello; I allow my water to sit in containers for a few days (usually about a week). I have learned to plug the necks of the containers with a foam plug that allows air movement in and out but prevents mosquitoes from hatching in the warm months. I now have enough containers for more than two water changes. I do not use bubblers, just let it sit.
The water is in clean containers and is also emergency drinking water if the need arises.
I have one six gallon potable water container and several gallon jugs. I have found that the plastic jugs that drinking or distilled water comes in do not hold up over time and will begin to leak. I find that plastic vinegar, clorox and auto windshield cleaner ( the kind with only alcohol) bottles are very sturdy. I clean them by rinsing them thoroughly. I will fill one up and let it sit a while several times before using for fish water changes. I pour the water into the washing machine or toilet so as not to waste it.
I have been doing this for at least three decades on tap water. Call or go by your local water company. They should have a copy of a current water quality report you can get and will be able to tell you what they use as treatment.
