with changes that frequent it wouldnt make a huge difference, but i would go with 2 slightly smaller changes per week.

question guys, do u hav to change water in the tank once a week even if the water is clean? or looks clean?

Depending on the bioload of the aquarium, at least once a week but if there are not many fish or they are smaller then every other week at the minimum. Once you add fish to a tank the water quality will start to go south regarless of how much you filter. With your fh I would think 1x week at 30-35% would be great.
