Exactly like my earlier fear of tapwater chlorine instantly killing
my fish. In fact I don't even put dechlorinator on some of my
Central American Cichlid tanks. Have we just busted a whole
section of the aquarist industry there?
And I utilised the same hose techniques as you did.
I actually place one end of the hose inside my tank,
turn on the tap and pull out the hose when the
whole length of the hose is filled w/ water. When you
pull out the hose from the tap mouth, gravity will suck
your tank water down.

I'm presently using a much easier way to do the weekly water changes in my
tank. Instead of dealing with filling buckets of water I just use a garden
hose siphon to take out about 50% of the water. Then I just connect the
hose
and add the water back in. I add a couple of capfuls of dechlorinator
while
I'm adding the water. I've never done this in the past fearing that the
chlorine would still be present and kill my fish. The water temperature
after the addition drops from 78F to 74F but the two heaters bring it back
up within a few hours.

It doesn't seem to affect my fish using this method and it's a whole lot
easier than the bucket method. Anybody else use this technique? Comments?
