How long does it take for dechlor to kill chlorine ?

  • We are currently upgrading MFK. thanks! -neo
I have posted this several times now:

The Clean Water Act of 1972 mandates that water suppliers must issue a water quality report at least annually to all its costumers.

You may not have noticed it when it came in the mail and tossed it out, or maybe you rent and the info never got to you. No worries however, because for most areas this info is available online.

Information that you might find useful is what chemicals (chlorine/chloramine), and how much of these chemicals are used to treat your water, Water pH and kH at the source, pollutants and heavy metals, and other info.

Start here: http://www.epa.gov/safewater/dwinfo/index.html. This link will take you to the EPAs web page and you can find your local water suppliers web page from there. Your Annual Water Quality Report, (or Consumer Confidence Report depending on location), should be easy to find from there.

The minimum is at the last home on a pipeline, not at the treatment plant.

My tap water is frequently 4ppm and above. I’m gonna die. :nilly: It is typical for swimming pools in Florida to be over this amount as well. However I imagine this is for only drinking water but dogs frequently drink out of pools (and kids too).

Whats stated is not the minimum, its what is used at the plant and it comes out of soultion as it is distrubuted through the system. I have been to the Water treatment plant that services my area and check my CCR regularly; They treat with chlorine at 4 ppm, average concentration as it reaches the user is 0.58 ppm, with the lowest being 0.03 ppm. Cl is at the low end at my residence.

Perhaps your test is inaccurate, over 4 ppm at the users end is not likely, as the state standard for Florida is to treat at the plant at 4 ppm

Big time false. Unfortunately you happened on some bad information on the way. I tested my water aerated and non-aerated and they tested the same. :( From my tests, it takes four to six hours (depending on the Cl2 levels) to fully dissipate by aeration.

I big time disagree, properly proportioned aerated water should gas off all Cl in 30 min or less, heavily aerated water in much less time. I have tested this in a water quality lab under CA DWR supervision. I suppose you will all want to see the data/results. It is unfortunate, but its not likely that I still have them. I did this as part of a lab when I was still in school and its likely since been tossed out.

Im confused, so dosing a tank then filling up is bad and I am better off getting a 55gallon bin, treating it in there then pumping it into the tank 4 times?
Yes but only if you give the buckets atleast id say a half hour total for the dechlorinator to work. Have you read the thread ? Im sorry not trying to be rude :)

This could kick the thread off again :)

its not a big deal........... dose the tank with prime for the volume of the tank and add tap water........:)


probably safe up to 50% change. if you need to change more do it twice in a row

as important is to keep the temperature stable !!

ya I read the entire thread, but alot of people asks things, and alot of people say things, and I am not exactly refreshed from sleep last night so my mind may not be all there. My gf has tap water and I fill the 5gal bucket up, dump the prime in mix it with my hand for a few seconds and dump it in. I have seen no reactions in the past few months.

So from what I get, fill bucket, dose, then give the prime the time to work to juice out all the chlor then dump it in. Man that would take a long time with a big tank

Ok, because I am tired of dumping 5gal buckets in the girls 55gallon tank. And would rather dose the tank and fill it up with a hose connected to the shower.
 
Your using the right method all I would say is give it atleast 5 minutes for the dechlor to work. As established even though the fish may not show immediate signs of stress it cant be good for them.
