What I have been doing is changing out 8 cups of water weekly in my 3 gallon tank. I use a liquid water conditioner, which adds beneficial bacteria that your betta requires for a healthy habitat, and also a liquid chlorine remover to condition the new tap water. There are several brands out there to chose from.
I use a small syringe from a pharmacy to administer the correct amount of conditioner to the new water. You will see an immediate change in your bettas health and vigor.
I keep the tank out of direct sunlight to avoid algae growth, and haven't really had a need for a complete scrub down. I think that a complete scrub down destroys the beneficial bacteria that is so important for aquarium life.
I also use a small biological filter, which is also an important part of the whole cycle.
I hope this helps.
