Why do some people suggest leaving water out for 24 hours/overnight...?

Question

...before filling their fish tanks or doing a water change?

If you suggest it for temperature reasons, keep in mind that the water added to the tank is supposed to be within 4 degrees of the temperature of the tank. If you have tropical fish, this simply will not work, unless room temperature at your house is around 78 degrees.

If you're doing it to dechlorinate, keep in mind that most treatment plants are now using chloramines instead of chlorine to treat the water. Chloramines take well over two weeks to dissipate completely.

The only reason I could see leaving the water out is to stabilize the pH (if you're in an area that uses hydrogen peroxide in the water - and even then you must aerate the water to remove all of it) - but I never see people suggest it for that reason.

So this is directed to the people that advise letting the water set out - why do you suggest it?

Thanks, all! Hope you're having a great afternoon!

How does letting the water sit out overnight improve oxygen levels? It's not getting any circulation (unless you put an airstone attached to an aerator in) - if anything, it's losing oxygen.

To the answerer that suggested smell - water out of the tap should never have a sulphur smell. If it does, your municipality should be notified immediately.

And to you people talking about temperature - read the question thoroughly - that's already been explained.

Answer 1

i guess its one of those things that were meant for removing chlorine but now it doesnt work because of Chloramines

Answer 2

They say that by leaving the water 24-H, those nasty chemicals will settle to the bottom, which really doesn't work that way. Some chemicals in tyhe water will never settle down.

The thing that I do in case of this scenario is to let my filter on with activated carbon on it so that those contaminant will be filtered out of the water.

What stresses cats is the sound of 'consistent silence'. IOW first ingredient you may desire to do is placed money right into a timer which permits the television to alter on at a time once you many times are at homestead. exceedingly a cat it is an indoor cat. The morning could nicely be began with a radio clock. I agree that a 6 month previous cat is extremely plenty a toddler and in want of companionship, as much as available. The kitten will proceed to exist a week, with a carer who cleans the clutter tray, feeds and cleans the meals bowl and differences the water. In iciness feeding moist meals is superb additionally, as no flies around to place their eggs. You in addition to have the income of a man or woman shifting the mail from the door, that is an invite for undesirable characters to assume that no one is at homestead. it fairly is significant that the carer spends time fiddling with the kitten and which you grant sufficient distractions, scratch posts, cat nips, alongside with a grass plant. a youthful cat desires comforting and reassurance. in case you reside close to a hectic street, and in case you have an high priced pedigree cat, it fairly is logical to maintain the cat interior. each and every of the comparable, cats could desire to stay outdoors or a minimum of have get entry to to the exterior worldwide as they improve older. Cats could desire to consume mice as area of their weight loss software. Mice grant priceless meals and supplementations, that are actually not available in commercial ingredients and the organic ingredients we purchase from the butcher or community supermarkets. So, for the long-term plan, it fairly is particularly merciless to maintain a cat interior. till you have not got the different thoughts, you may require a particular section interior the homestead the place the cat can behave like a cat. make optimistic your cat connects with the carer, in any different case the journey could desire to coach annoying on your cat. human beings think of that cats are actually not related to human beings, that is no longer so, they relish socialising and exceedingly receiving an avalanche of interest whilst it suits them, for sure! LOL interior the guideline e book of the cat, it is your honour and privilege to proportion on your case, his homestead!

Answer 4

I would probably say that it's because some random person thought it would be useful and it actually isn't. But it managed to get perpetuated and it's just one of those things that people just accept for no reason and don't really think about why.

Answer 5

Its one of those myths which are perpetuated through ignorance. I once believed it myself!
Not that I ever did it...with 4 tanks holding 1000's of litres of water I wouldn't have anywhere to store it all...give me tapsafe chemicals every time :D

Answer 6

I don't know the real answer to your question, but before you go "knowing it all" just know that an air stone or air pump does not actually add oxygen to the water, it only disrupts the surface allowing for more oxygen to be dissolved.

Don't attack people who are answering a question that you asked, which obviously you don't really need the answer to.

Answer 7

I'm with you, I think it's pretty pointless. I add mine immediately after adding dechlorinator and have not had any problems.

Answer 8

it is because the temperature of water is important. You don't want to shock the fish by throwing him in COLD or HOT water. this could kill him so leaving water out overnight makes it room temperature and fine to put your fish into.

Answer 9

it's called tempid water which you use for your house plants refilling water levels in your car battery and is a must for a fish bowl. also the radiator in your car needs it to stop corrosion.

Answer 10

might be linked to the oxygen level in the water
the more is dissolved in the water the better for the fish
seems reasonable....
