Fish?

I have a 7g nano. On it, I have a filter that holds two filter cartriges with carbon. I would like to get this tank. Considdering that I am doing weekly 3g water changes on it, is a filter necessary? The only things that I would need to keep in the tank are the heater, powerhead and a bag of carbon/Purigen.
I have considdered this tank because of the built in rear chamber, however I have really taken a liking to tanks that are clear on all four sides.
What to do?
