If you let chlorinated water sit, will it eventually turn safe to use ina tank? In other words, why is distilled water safe to use, and what makes it distilled? Thanks guys!
Well yes... After a few days, in sunlight especially, the chlorine will go away. But distilled water is a whole different thing. It is boiled super hot, then the evaporated "steam" is collected. It has no minerals or ANYTHING in it. So it also has a bad buffering capacity. That means that it is not stable enough to maintain ph, and that the levels in the water will fluctuate. I don't recommend using distilled. Use tap with a dechlorinator, or use spring water-- which you may have to treat as well.
If water is allowed to sit for 24 hours the chlorine will disapate into the air, but Chloramines won't so for most people it's safer to use a dechlorinator to prepare their water.
Okay, thanks. I tested my tap water and it seems to have not much to none chlorine in it already. I bought soem conditioner though, so all is well. Thanks for your help!
