Uhmm, I'm not sure if I my english skills are so rusty that I sometimes say
something totally not understandable. But I do change about 50% _once_ a
week, closer to 70% if I forget to check the water level from time to time.
And I usually tend to overfill the tanks because using hose straight from
the tap is too easy and again I forget to check the water level.
Self-inflicted floods are always near in my household (yes, I am a woman).
We have clean tapwater here in Finland and I don't have to prepare the water
before putting it to the aquarium. So one large water change per week isn't
as stressing as it sounds.

It was stripped for the photosession. It is usually well hidden behind some
plastic plants and is almost non-visible. :)
