chloramine dosen't gas off like chlorine does so you letting chloramine treated water sit does nothing
+1
But I treat for water added, especially with the smell of prime, that stuff can't be good in high volumes. But here's my little trick, I don't ADD all of the dechlor at once, I do 50% wc, so I add 1/2 the amount when I turn on the hose, and the rest when its at halfway, it has worked very well, and I save a little cash. It all depends on how much product your water company adds.
And when I do changes on small tanks, I take a cue tip and dip it in the bottle of prime and toss in bucket, way to hard to pour 2 drops lol.

Most cichlids are hardy enough to where you don't even have to use dechlorinators.
And as far as this comment;
Completely false. Both chlorine & chloramine are toxic to fish, including cichlids.
Both chlorine &/or chloramine can cause long term damage & even death to fish, in some cases even at low levels, especially young fish which are typically the most sensitive to these substances. Free chlorine can cause acute necrosis of gill tissue in fish, the younger the fish the worse it can be. Chlorine also has the potential to wipe out most/all of the bio bacteria in your system. In short chlorine is an oxidizer, that can burn a fishes gills & kill cell tissue, sometimes even at low levels.
The amount of chlorine and or chloramine can vary greatly from one municipality to another, as well as from one tap to another, and can also vary greatly throughout the season. There is no way that anyone on a public forum can possibly attempt to tell you what a "safe" amount is in your case unless they have the specs on your local tap water at your user end. Water temp, pH values, etc can also determine how 'safe' certain levels of known toxic substances such as chlorine/chloramine can be on fish.
According to Edward Noga, a professor at NC State that is considered an expert in the disease & health of fish, chlorine levels as low as 0.10 mg/l (which is very common in many tap water levels) can be accutely fatal in aquaria that has low levels of organics. (as in a new set up) Others have found residual chlorine levels as low as 0.05 mg/l to be toxic to certain species of fish. Many areas of the USA contain 2-3 mg/l of either chlorine, or chloramine.
There has been a TON of work done in this area over the past few decades, by a number of researchers, such as Tompkins & Tsai (1976) for anyone that is interested in understanding just how toxic both chlorine & chloramine can be in a closed system that contains fish.
The fact that a fish doesn't die shortly after performing a water change sans any type of conditioner in no way means that the exposure hasn't caused damage to the fish.
I have personally seen (and read here on MFK) a number of cases where total die off of bio-bacteria as well as fish, was caused by a large water change, where the owner forgot to add dechlorinator. I have also seen total (or at least a massive amount) of BB killed off by rinsing filter media in tap water. Enough to cause a major ammonia spike in a semi established system.
Both chlorine & chloramine have the potential to totally wipe out the bacteria in an aquarium, and cause both short & long term health issues in fish.
Again, this will be dependant on numerous factors, and can vary greatly from one hobbyists situation to another, and what may be safe for one person, could prove to be a disaster for the next person a few cities or towns over.

Everythng that you need to know about water conditioners & how best to use them should be contained in that link.
Hope that helps.

As previously stated;
There is no single definitive way to treat water (if one even needs to treat it) that will fit every situation encountered by every member here on MFK.
For "some" people treating the entire tank volume (even if adding dechlor in stages) makes perfect sense, and is not a waste, but an added layer of protection for their fish.
I'm not sure why that concept is so difficult to grasp for some people?
