How long to dechlorinate??

They will so long as contact and time are great enough. Catalytic carbon is most effective.
At a homebrewing group we used a 3 stage inline filter then had the water tested. It worked quite well.

So I am a new grower, and despite some of the notions that there should not be enough chlorine in my water to matter (I have looked up the water reports from my company and they only use chlorine not chloramine) I bought some aeration tubes/stones to toss in some 5 gallon buckets. The one thing I can't seem to find a direct and obvious answer to is how quickly a well aerated 5 gallon bucket of tap water will dechlorinate. I have seen some people say 2 -4 hours, and others say 24 to 48 hours... The whole reason I got aeration is the claim that doing so would speed up the process. I am simply not wanting to interrupt or slow down the activity of my microherd, or at least affect them as little as possible within reason.
I was already under the assumption that 24 hours without aeration was enough for most peoples tap... If I still have to wait that long even with aeration I will probably just use one for tea, and keep the other as a spare. I read a post mentioning something along the lines of 2ppm chlorine (is this a lot?) taking something like several days to a week to evap from an open 10 gallon bucket, but once again that didn't seem to take into account a rolling boil level of aeration. Is it safe to say 2 hours bubbling away in a bucket should be good, or does aeration really not actually speed it up all that much?

my munincipality sends water report that lists amounts of chlorine so I hope it's chlorine and not chloramine but would not assume for sure. like city hall knows the diff between the two, please. i read something pretty believable to me that chlorine will take about 5 days to disapate to some specific level i don't recall if just sitting in an open bucket, 24 hours if being bubbled, and 24 hours in sun. so i bubble mine in the grow room under lights for 24 hour. i don't know if it work but that what i do. I don't believe sitting is enough. Killed many fish in the fish tank and i don't keep fish no more. Oh I wanted to add the old fluoride problem comment to add a twist to the thread

if your tap water is good enough not to sap or impurify your precious bodily fluids it will be fine for your plants

One factor is temperature. That’ll effect how quickly chlorine is removed.
For a 10 gal bucket that’s well aerated id day 12-24hrs. Again temperature will play it’s part in how long.

Thanks for your response! I plan to use 4 gallons of water in a 5 gallon bucket, the temps at the moment are around 70 degrees, I wouldn't plan to let it get down much past 60 degrees come fall/winter. Perhaps 4 to 5 gallons would take less time at cannabis comfortable temps? I guess even if it takes 24 hours to be sure, its better to be safe than sorry.

3-5 days for chloromine; which i think is used most places
