How much water do you change every week?

Actually glad you raised this issue - it is an issue, at least in my part of the world. My water goes on the garden.
I change about 10 - 15% / week on 70, 100, 70 and 140 litre tanks.
You're kidding, but I saw this in a shop I had never been to last week.
I was watching the water drain out of a tank while the guy was talking to me - it had some sort of blue discus (?) in it, and it was draining right down so the fish were on their sides.
I say (trying not to sound horrified), "What's going on there?"
"Water change," he says casually.
I'm sorry...but that's the most funniest thing I've ever heard..not the draining 96% part but the part of keeping your fish in the tank when doing a change like that/????
Usally if there was a need to do a change like that I'd move them to another "container" or tank.
i've got a 29gal and do about 10 - 15% change every 10 days.

The best way to conserve water is to keep it in the system in which it came from. Water really isn't in shortage globally, what I mean is that there has always been the same amount of water it doesn't go away, it just moves around. If you use well water and septic, you would need to put water that you used back into the water table. If you use public water and sewer, you need to keep the water in that system. If you put that water into the ground, it ultimately causes a shortage of water in the system. It would be better in this case to just dump it down the drain to be refined. This of course brings up other issues of energy conservation and pollution which can only be solved by wide spead use of clean renewable energy (like solar power) but that's all a whole other story.
I change ~50% in my tanks each week, usually Sunday.
The water from my tap is between 20 and 40ppm too. I have called the city's water guy several times and what he tells me are, none of his test readings are every that high and the reason I am getting high readings with my tests, is that there are certain things in the water that can register as a false positives, such as chlorine. I don't know if he was just telling me this so I would leave him alone and I don't have enough of a scientific background to tell if he was just giving me a pile of bologna. He also told me, if I was worried, I should put plants in my tanks....

yeah Beth,
I'm just not buying it. I taught a semester of environmental geography at a University and have studied enough of it to know that the water that goes down your drain doesn't simply recycle through your system and end up coming back out of your faucet.
I think thats something people like to tell themselves to feel better about 20 minute showers and high flow toilets

that fun little powerpoint speaks to my issue with this theory - water treatment plants remove ORGANICS from the water and then reintroduce them into the watershed, however water contaminated by inorganic is essentially lost from the column. IN essence its wasted. The problem is people put all kinds of inorganics, some really nasty stuff, down their drains. A TINY percentage of the water you put down the drain makes it back into the water column as clean water.
Look past the first page and check out the next few on that link. (didn't want to seem like I was just "barking")
