Changing The Water

[L u]

How long should I wait before I change the water? And how much water
should I remove? (5 gallon tank). When it's time, I really want to
remove all the water, and clean all the decorations, and of course the
gravel.

If I don't clean out the tank, and I just remove "some" of the water,
the gravel will stay dirty.

change as much water as needed to get rid of ammonia or nitrites.
change water to keep nitrates under 20 ppm.
