to be honest, most of the time you dont even need dechlor, but you put it in just incase. Just put it in either before you start, or while you are doing it.
What I've been doing is adding dechlorinator for my tank before pumping the new water in. I have a 30 gallon tank, so it's 1 pump for X number of gallons. Whatever this is for the whole tank, I just put it in.
For temp, you can adjust it first before you start pumping it into the tank. And even after, if the temp shifts, like a lot of faucets can do, you can go back to your sink and adjust it. I often err on the side of a little bit too cool than a little bit too warm, as I already keep my tank around 78-79 F. If your water changes are a small percentage each time like they should be, your temperature shift isn't going to be more than a degree or two. the fish won't mind and your heater will get things balanced out in no time.
mmmm, I'm gonna have to take a second look at one of these then
I guess the chlorine isn't an issue anyway assuming you all have healthy tanks, which I'm sure you do
What's the suction like on one of these? comparable to a standard siphon cleaner? I have smallish sized gravel ranging up to 4 inches in depth, I assume I can insert it into the gravel to the bottom of the tank and watch it clean - no messing?
