Don't teach others, what you don't know yourself!!! A wrong advise is worst than not advising itself.

You wiped out all your shrimps whenever you do that, which clearly shows it is a WRONG move yet you are advising others to do what you did. What is your motive? Trying to get others in the same plight as you gotten into?

In such instances (happens once in awhile), I will 'siphon' the water on the surface using a container (tilt sideways, let water sip into container slowly). I will also use a air/oxygen tube with water inside, touch e bubbles and let e bubbles enter the tube.

When we change water, we usually suck out from e middle or bottom of the tank thus omitting the top.

zzzzzzzzzzzzzz. nvm

which is why it's advisable to have some surface agitation. not too much like splashing but a smooth ripple to encourage gaseous exchange.
