Stagnant Water.

[tanzen]

How long does water have to sit out to be considered stagnant?
And what exactly is so bad about stagnant water?

When i make new water for water changes, i add the dechlorinator/etc. and then spray the water from my sink into my bucket. I know you're -supposed- to circulate the water while you let it sit out, but i dont. I let it sit at least over night, but sometimes longer. Usually no longer than a couple of days though. Is this bad?

i put the dechlorinator in the bucket, put the tap water in the bucket, walk the bucket to my tank and pour it in...


ive done it that way for years and never had a problem...

I do as Sean W does... Fill bucket, use conditioner, put in tank.

No need to let it stand if you're adding conditioner.

I fill tank from hose pipe - then add dechlor.
Really you don't need to let it sit for the dechlor to work.

Yea, i know that i dont need to let it sit, i just let it sit over night so that the water will become room temperature (water comes out of my tap ice cold)

And i usually make my water late at night before bed then i do my water changes the next day.

I was just wondering if there was anything wrong with stagnant water.
So i'm guessing there's not?

Water left to sit overnight isn't going to be stagnant.
Stagnant is when the water becomes foul and stale - often seen in ponds with no circulation.
Using stagnant water would not be a good idea. Using water left to sit over night will do no harm (providing it can not become contaminated in that time).

Stagnant water is due to no circulation/water movement and the problem is that it normally causes a lack in oxygen. Why are you leaving your water out to sit? If you are adding dechlor, you should be able to add it straight to the tank (as long is there isn't any C02 bubbles in it.)

He;s letting it sit so that the water will become room temperature.

Is it a cold water tank then?

Why not just measure the temp out from the tap? Just some suggestions to save time and make things easier.

he also said that the water that comes out of his tap is ice cold. Please read all of the posts, guys

My tap water comes out around 5C
When I do a water change adding this straight to the tank from the hose the drop inside the tank is minimal (2-3C) and the fish love it - especially corys.
I guess it depends on what fish you've got.
But either way it's OK to use water that has been left to sit overnight, so long as it's protected from accidental contamination - water won't become stagnant overnight.

the water becomes stagnant, the moment you put it in the bucket.
I am afraid stagnant water is not foul. that is feted water. stagnant means NO MOVEMENT, and has nothing to do with how healthy it is. indeed Lillys are grown in stagnant water (prefer to be i suppose), ADF's prefer it, indeed a few fish thrive in that environment. true if it is left, without agitation or replenishment, it will grow feted. i agree people have the, misapprehension, stagnant means foul though.

As stated i leave my water to sit in containers over a few days before adding just because it saves time for my smaller tanks, with my big tank i just add the de chlor and add straight to tank, in the winter when waters cold i add a mix of hot/cold straight into the bucket and check temps are same then add, if you guys remember we had a very cold spell and when i did a water change i never checked temps,done same for years, however temp dropped alot and two silver sharks went crazy crashing and banging then a better word to say 'collapsed" Took me 30 mins to bring them round and two days after one died, so mate leaving water to sit is not a problem at all, doing it this way aswll i do not use dechor as much,,I know of people using rain water collected in water butts and sat there for a few weeks...

Also no doing this is not going to cause any problems at all, we all have our ways of changing water, what ever suits mate, but no the water is not bad as boboboy stated its only stag because its not moving or anything, my snakeheads much prefer not having waterchanges as a result i change maybe three times a year, as long as reading indicate waters ok i leave well alone

True enough stagnant doesn't have to be foul or dirty, but in reference to water it usually is. Stagnant isn't usually used to mean "still water".
People don't say "I'll have a nice cool glass of stagnant water please", but do say "eew look at that stagnant pond".
I guess one of those cases where the possible meanings of a word and common meanings aren't always exactly the same.
Of 4 definitions on freedictionary.com only one of those doesn't mention the water as been foul, dirty or stale.

humm, not in the Oxford dictionary. Foul or stale, is a "Common", usage, not the definition. you should look feted. but use a real dictionary or one, at least, that does not give "common" usage as a definition.

there is more to this than just an argument. the difference is important. as shown by plants and animals who live, breed and thrive in a stagnant pool. these same organisms would, die, in feted water. feted stagnet water is dangerous, stagnant water, simply does not move.
