Can water sit too long for aging?

Question

I have used a dechorinator in the water which also takes care of chloramine. It has sat for about two weeks in 2 sealed 5 gallon containers. It is for a 55 gallon tank. Can the water sit too long before being used? I am guessing no but I do not want to take the chance. Someone knowledgable in the area please help. Thank you

Answer 1

Water can become stale, and especially if you have hard water, the dissolved solids can settle on the bottom and make an unattractive gunk on the bottom. Once added to the tank, though, it shouldn't be any problem at all. Although, the sealed containers defeat the purpose of airing out untreated tank water - you let water sit if you don't have dechlorinater so the chlorine and chloramine can dissolve out and into the air above.

Answer 2

Basically, no, water can't sit too long for aging, but it can collect materials, odors, etc from the air and of course dust can settle on the surface. So if you will have water setting out for very long, it's best to cover it with a towel.

remember that chlorine can evaporate. however, chloramine will not!
