I use 5 gallon buckets and I would love a better way to change the water, but the night before I make the change I fill the buckets with water, add dechlor and put a bubbler in it overnight.
Then I siphon the old water out into other buckets and dump it down the toilet (where waste should go)
If you are changing a large portion of your tank then yes, you do need to be concerned with the chlorine, O2 and temperature levels. Generally you should only be doing 15-25% changes though and the chlorine and 02 that will come in won't be extreme. Plus you mentioned that you put a bubbler in the bucket so you are actually putting more o2 into the tank than you probably would straight from the tap. Temperature is pretty easy since most sinks allow you to adjust that but if you have to use an outside spicket or something then you might have problems. If for some reason you have to change a huge portion of the tank then the best way is to use buckets or take the fish out while you fill the tank back up so you can dechlorinate and let temps adjust.
Others have asked if you need to treat the whole tank with dechlor or just enough for the new water and I think it depends. If you are using buckets then just dechlorinate the water in the buckets before it goes in. If you are using a python and filling straight into the tank then I would use enough for almost the whole tank since the chlorines and heavy metals will have dissipated into the entire tank and using a little more ensures that the chlorine will be detoxified fast. Personally I use Prime by Seachem since only one capful treats 50 gallons and the product is pretty cheap compared to Amquel or other good products which use one capful for only 10 gallons.
