Water changes on a 20g

I do a 10% change every weekend on my 29 gallon. In a small system I would not want o go much longer than that, Parameters change too fast.
 
either can work -I prefer weekly water changes on my 10 gallon because it helps the tank stay looking good and I enjoy the 30 min or so it takes to clean the glass, siphon out algae and clean the sand and then add new water each week. but I think what is most important is that you have a regular schedule and stick to it.
