Dechlorinator isnt "instant", but it is very quick, it's like bleeding into a bucket and the water turning red, thats about the best example i can give :>

Your assuming your tap has a lot of chlorine to start with. Like I said test it, its easy if you know anyone with a pool or spa. Or you can buy liquid or test strips(this is the only place I would suggest test strips). First off you add the dechlor to the tank before adding the new water. The new water lets say contains 0.5ppm of chlorine. Even without any dechlorinator in a 50% water change chlorine will still dilute to 0.25ppm a reading that will neutralize in an hour if not faster on its own. There is little harm a small amount of chlorine can do to ALL the bacteria in your tank before it gets used up. Pools are kept at 1-2ppm to keep things from growing. Even if you by chance lose some bacteria a healthy colony can spring back within half a day if not faster. You would not see anything on a test kit, bacteria are always dying and reproducing in a healthy tank. Now if you add dechlorinator to the mix you are both neutralizing and diluting the chlorinated water you add to the tank. If you use a full dose of prime for the water added you likely have over 6 times the dechlorinating power you need.Ok, thanks for the replies people! I am getting to see your point but wouldn't the chlorine take even less time to kill any bacteria you may have growing in you substrate/ornaments than the dechlor. Or does this not matter? Lets just say that it takes 1 mintue for the dechlor to completely disperse, how long does it take for chlorine to take effect on bacteria. I am starting to see how dumb the idea I was told is! You learn a new thing every day eh![]()
Also what about other things in the water? (eg. heavy metals) How long does it take for the dechlor to react with these things? A fatal amount of time... I don't think so!
Wow, when I started typing I thought one thing and now I totally agree with you guys![]()
Thanks everyone!

Well the question then is how much copper? My previous place had at least 0.13ppm according to an old water test. Copper is toxic for invertebrates, but it is also a essential mineral. Considerable copper will kill shrimp and such. Treating the tank with copper based medicines is one way to kill shrimp. There is a big difference in the amount of copper used in those medications and the amount of copper normally in tap water. Unless your tap water tastes like pennies I honestly would not worry about it. Basically no copper is bad(except its in most fish foods anyway). Traces of copper is good. Large amounts of copper is bad for inverts.Thanks for the quick reply. You've defo put my mind at rest! The only reason I mentioned the heavy metals is because we get huge amounts of copper in our water for some reason and I just wondered how bad it is for invertibrates and fish. I guess they have to be exposed for longer periods of time with extremely high concentrations to be damaged by it.
Why then do some people worry about adding copper based medicines to tanks with shrimp in? Is this just a myth, or perhaps it's because they have to leave it in there for long periods of time without taking any out...
That'll make things much easier for me then, no more buckets for me![]()
