All good advice I read so far. I use similar method for pwc in that i dd dechlorinator then new water from the python. Incidentally I found out recently that Chicago does not use chlorine. I still condition my water just in case, but it was a nice perk. I hope to move to California soon, and they use chlorine, so it will be an adjustment.
I also use a bucket method to top off my tanks in the winter due to faster evaporation. When doing this, I condition the bucket water, wait a couple seconds and then add it to the tank.
Regarding bubbles, in my "tiny tank" which has dwarf pea puffers and bumble bee gobies, the puffers enjoy disturbing the bubbles after a water change. Every water change ends with then racing around and attacking the bubbles that rest on the stems of plants. It's pretty funny to watch, the bubble hunt.
