What should I do about water changes????

10% per week and keep temp from changing more than 2 deg, in 24 hours.
76-82 F is good.

fine nothing is out of wack. Should I change the water to keep it
fresh, or should I leave well enough alone.

The reason for this question is that I have an anemone that is balled
up. He was doing well as of 3 days ago but the last few he kind of
sits in the middle with little to no activity.

What about the temp. should that be set at a certain level. My tank
is a reef tank with three fish (20 gallon).
