How long does it take for dechlor to kill chlorine ?

  • We are currently upgrading MFK. thanks! -neo
Man I am glad I am on well water or my fish would have been screaming each week. My gf's tank I use a 5 gallon bucket and mix prime then dump it in but I am getting lazy and want to hook a hose to the shower and fill er up. But if I drain the water then dose the tank THEN fill it it, the prime doesnt get diluted and less effective?

I know when I get my big tank setup in like 6 months or so I will have to use prime and dumping prime in then putting in 200-250gallons of water just makes me weary that the prime will be all used up before the tanks full. Ya I know I am :nilly:
 
One thing I wonder since we are on the subject...say you put Prime in a tank of water and theres no chlorine in the water for it to neutralize....does the Prime just stay in the water waiting for CH to take care of...does it dissipate even tho theres no CH...follow?

Like for the ones that add as they are filling the tank with water...if you treat for X ammount of water....will the prime be compromized befor the X ammount of water is added back into the tank?
 
It is either evaporated (I think) or becomes increasingly inactive I would imagine.
 
a good topic ,,, someone once mentioned to me , let me think ,, something along the lines of ,, ''well the water has been sitting in my house pipes for longer than its gonna sit in a bucket ''

i am no scientist but i remember it made my brain tick ,

I believe it needs oxygen for the chlorine to dissipate. And most people use their water for at least ten seconds a day. I could be wrong here. :)
 
As far as water sitting in the pipes....yes the chlorine needs air exposure to dissipate...but also many municipalities now use chloramine rather than chlorine because its much more stable, so you can't just aerate and let it gas off like you would with chlorine.

Yep
 
No offense, but can you site one of these studies? I would greatly like to read up on the subject more from a scientific point of view.

Google around a little bit, you'll find what you need as I don't know at what level you would like to start at.

If you would like to see how fast prime would disperse through your system use a drop or two of food coloring and watch to see how fast it gets dispersed. If you would like a better picture use a pinch of finely ground flake food. I think you will see that it gets dispersed pretty dang fast.

The milk example is a pretty weak explanation. sure it spreads slow in water with no movement whatsoever. Take two glasses half full of water for example, put in a teaspoon of milk in each and then stir one with a spoon. Im pretty sure the milk will be pretty well dispersed within a half a second in the glass with the spoon.[/quote]


Enough of these comparisons, they're all the same.

Who ever said there would be " no movement whatsoever" with the milk? The demonstration was adding the milk just like you'd add dechlor, I'm not doing a commercial here, I'm not hiding anything. The dynamics of the fluids won't allow for instantaneous contact of all the water molecules.

And if your going to "stir" your aquarium that hard the fish are going to be rather damaged.

Nice , I am now using a whisk and allowing the water to sit 15 mins before adding.This never failed me in the past that is for sure.

I merely asked you to cite because you stated they had been done and you seemed a viable source for a link or two. Im plenty familiar with Google. Again, no disrespect meant.

My using food coloring as a basis to show the hydrodynamics is about as close to scientific as the common person can do. No frills. Just facts. Pure Science. And you are correct in one way, the dynamics will not ever allow for instantaneous contact, however, with the flow rates we typically see on our aquariums, we can expect total saturation within seconds.

How, do you ask? Lets take a 50% water change for example. tanks is drained to 50% and enough conditioner added as per directions on label. Prime says to dose for tank volume. Say we are working with a 30 gallon tank to make things easy. Now we have 15 gallons of previously dechlored water that now has an equal dose for another 30 gallons. Now we start adding tap water that has chloramine/chlorine. As that water is put into the system with the previous 15 gallons plus declor, the movement of adding the tap water to the tank water will homogenize both together. Is it instant? No not at all. Is it really really quick and ALMOST instant? Yes very much so.

According to your theory, my 1-7 day old fry should be dead and all my other fish should be gasping at the surface from so much gill burn. Yet they all live on happy and healthy.
