Almost never.

In 3-1/2 years I have changed maybe my tank volume (120 gallons) once in total.

I keep meaning to set up a system with a garbage can and pump to do monthly 20 gallon water changes but I never get around to it.

Mostly everything is doing OK though with nitrates varying from zero to barely measurable.
