jb117, if you've got adequate biomedia in your tank, you want to be doing partial water changes about weekly. I have the XP3, and I do 30-40% water changes weekly.
If you're in doubt about the quality of the water, test it. You can get kits for testing ammonia, nitrite and nitrates in aquarium supply sections.
Turtleman17, how often you change the water depends on factors like the size of your tank, the size of your turt, how much water you have in the tank, the filter, if you have other creatures in with the turt (fish, for example), etc. The smaller your tank, the smaller your filter and the less water you have in the tank, the more often the water needs to be changed.
