As title states. Anyone know how long?
I also put in Tetra Aqua Brand. Aqua Safe (Makes tap water safe for fish). I have heard it can take a few hours or 24 hours? Just wondering how long I should de-chlorinate the water. My yellow labs started breeding after I did a 50% water change 2-3 days ago. So I need to set up my recently purchased 10 gal tank from Rogers.

Thanks in advance, Clint.

i add dechlorinator to bucket, fill bucket, dump in tank.
thats pretty much it.

never had a problem

Yep that's basically what I did but I have read on google that you can use it immediately, I have also read that you should let it de-chlorinate for a few hours and last I have read that you should leave it for 24 hours. Would like to hear more experiences from you guys out there :)

Thanks Radiance.

Dechlorinators such as Aquasafe work instantly. If you are letting the chlorine dissipate on its own without adding any dechlorinator then you would need to let it sit for 24 hours.

Ok sweet. Time to put more water in the tank in a bit then :)

Thanks for the quick replies guys. :)

I'm not sure about the Tetra Aqua Brand, but if you are doing it naturally then it depends on how your poured the water.

Chlorine does not dissolve in water naturally so if you leave it it'll naturally gas out. I understand that if you just pour the water it can take up to 24 hours to remove the chlorine. The method to remove the chlorine is to aerate it. What this means is to expose it as much as possible to air. The best way is to use a shower head, and agitate the water as much as possible (if you have a good nose, you can smell the chlorine coming out). Also the carbon in your system will remove the chlorine as well.

What i personally do is pour the water into a bucket using my aerator on the tap, and hitting the side of the bucket (so it splashes more). I then fill my tank up with air tubing (yes... it takes forever). It takes a few hours for all the water to go into the tank, but I can remove the chlorine without using the chemicals (which can be costly if you have a huge tank).

I admit I'm actually not sure what percentage of chlorine is being removed with this method. If anyone is curious I could look into this... (I'm sure its addressed somewhere in my water and wastewater treatment textbooks....)

WOW!
So if I'm not reading this wrong, you're telling me that you dun even need dechlorinator to get the chlorine out of the water? All you have to do is pretty much "splash splash splash" for a long time to get the chrlorine out which is aerating it? Cuz this sounds very interesting!

Yes, you are reading it correctly.

I actually know a friend who has a fish pond who does this. He strung a garden hose up a thick chain (like 8 ft high), and lets the water trickle down the chain, and then into his pond. And I'm sure he'd know (considering the fact that he is a University Professor in water treatment...).

This is getting really interesting!

So lets say if I had a bucket of tap water! I slowly drip water in the bucket... lets say two drops per second! By the time it fills the whole bucket which will be quite a few hours later, the chlorine should be lower that from the tap? or could even be next to none?

That's interesting. But sure don't have patience lol. I just wanna dechlorinate the water and put in tank. Using air tube to fill it up sounds like a long process of waiting hehehe ;).

Not so fast. :) Chloramine can be used instead of chlorine for water treatment. Unlike chlorine, chloramine is quite stable in water (it does not dissipate).

Haha... something like that. I'll take a look at the manuals of practice when I get to work tomorrow (Just to make sure I'm not tell you crazing things). I'm sure there's an equation somewhere that'll tell me the rate of chlorine removal.

Well there's benefits to this method as well. You ensure that no sudden changes in the water chemistry and temperature occur as well. So if you are lazy you don't have to check the water temperature to make sure its exactly the same as the tank. If you take a long enough time the heater will take care of it and the fish won't notice the difference. Plus this is why I watch TV and do a water change ;)
