Does anyone have experience in ageing water in the blue barrels (30 or

bung hole open and how long it takes for the water to be safe.

I am in San Jose and some of the water is chlorine treated and some is
chloramine treated.

I am also in San Jose. You can effectively age tap water to get rid of
Chlorine, especially if you agitate or aerate it. But that is NOT a viable
way to remove Chloramines. Just use Amquel or Prime and be done with it.
If you need large volumes of water (100gallons per week) and want to save
money, you can investigate some of the sodium thiosulfate-based dry powder
products available. But a $5 bottle of Prime lasts me a year.

Thank you. That was very helpful.
