Actually, if you read all the way through the second link, it kinda makes an argument FOR 100% water changes by saying that is the only way to get rid of nitrates completely.
a 100% will not harm your fish if done properly. ive done about 10 100% wc's with no ill effects at all. as long as all the perams are the same or damn close i see no problems.
why have i done 100% wc's some might ask? well swapping out tanks or moving tanks is the reason for me, other than this i see no reason to do 100%wc's. i think i have had success though due to the fact that i change out atleast 50% of my water aleast once a week, so thefore my tanks perams are really close to my taps perams. and i always refill with water that is whithin 3-4 degrees temp.
i have never lost or caused any of my fish any sickness from doing 100% wc's. im shure there have to be some slight problems with doing this but i have yet to see them.

This is why I have five 5 gallon plastic gas cans that have never had anything in them but aquarium water. Between that and the water I put in coolers to transport the fish I save more than half the water of any tank I move, thus completely moving a tank without changing 100% of the water.
I do have to say that I find it hard to believe that you have moved a tank at least 10 times, not saved a drop of the water and never lost a fish. Moving a fish tank is a VERY traumatic event for the fish (and the aquarist), to tell me that you never lost a fish in a move seems like you are not being entirely truthful here. Maybe you are like Andy Pettit and misremembered?
But it really is...isn't it? I mean when you do a water change you are taking out just a portion of the water, thus a portion of the Nitrates....the declor you add actually removes them...right? If you took all the water out and replaced it all the nitrates wouldn't be there, of coarse you would have another cycle to go through, thus the reason not to do it, besides all the stress it would cause. For the record, I am not for 100% water changesHawkfish3.0;1811522; said:
I have done it a few times when moveing though, or setting up a different tank for my fish..and actually I've never lost a fish.
The easiest explanation is that by totally draining your aquarium, it will unequalize the effect of gravity with in the aquarium as shown in this formula- W- E3/P =G-- so as you can see, the effect will not stay limited to the localized area. This has the compound effect as the result will exponentially increase until its effecting the gravitational pull of the earth itself. If not remedied straight forth, eventually the planets will cease to align themselves properly. Next thing you know, the water won't even stay in the aquarium any longer. You wouldn't want that, would you?
