What about dechlorination? Do you have well water?
The self-piercing saddle valve is adjustable... you can drip, trickle, flow or blow with the turn of the little lever.
There's a couple of things about dechlorination. First off, I didn't use any dechlor for two years because there isn't much added where I live, and apparently they don't use Chloramine. With adding water very slowly I never noticed any stressed fishies. Now I am adding Prime, just to be on the safe side. If I continue my once a week water changes, I will just add the correct amount of prime when the changing begins.
If I go to daily water changes rather than weekly, I need to think about it a little more. If they are small enough (say 10 gallons per day in a 100 gal tank) I don't see any issues as long as our water provider doesn't use Chloramine (got to call them and find out if there are any future plans for this).
