Chlorinated Water

[Phil Slaton]

I'm having 3000 gallons of fire hydrant water delivered for use with my trout raising operation.  Never done this before.  I have commonly used my pond or well water ... no chlorine.  Fire hydrant water is common tap water ... it contain chlorine.  How long do I have to let the water sit in the tanks to allow the chlorine to dissipate ... with aeriation and without aeration?

 

Thanks!  phil

Phil-

  That's a lot of water to declorinate either way.  The chlorine will dissapate quicker with the airation than it would without.  I can declorinate 300-gallons of water in a few days (3) with a 500-lph aierator with a large airstone but this also depends on how much chlorine is used in the domestic water supply, temperature of the water and if you are doing this indoors or out (sunlight, wind movement must be taken into consideration).  This is a difficult question to answer so I apoligize on being vague.

Thanks Leo.  I will be dumping the water into 3 - 1200 gallon tanks that have aeration.  The tanks are in a green house that has a roof shade.  I suppose that I can just turn on the filter and aeration, open the shade for full sun  light and run the water for a week and it should be fine ...

Your welcome-

  By dividing the water into smaller lots, the chlorine will dissipate a lot sooner then if you left it in one lot. Keep us posted on the progress, a lot of new comers would like that kind of info.

[Phil Slaton]

Yes, thank you.  We will also test the level of chlorine in the water after we put it in the 3 tanks with our test kits.

Phil,

As Leo stated aeration will make it go faster.  The surface area open to the air is important.  The sunlight is not a factor; but opening the green house to dissipate the gases so they do not get reabsorbed into the water is.  The more aeration the quicker the process of declorination will occur.

Thanks Craig.

Make sure that the water is treated with only chlorine since if it is treated with chloramine it usually takes more effort to break the chlorine/ammonia bond in order to let the chlorine off gas.  UV or sunlight can assist in this but getting chloramine to go away by bubbling it in a pool under the sun can take weeks instead of days.

Definitely good to know you are planning to use a test to check your progress.

Are things so dry there this season that you have to haul in water?  Sorry to hear that.

Yes, we haver not had our usual rain fall.
