I would just for peace of mind!
Mainly because, if something did crop up, you know exactly what is in the tank as far as the water quality goes and would be ahead of the game. I have always tried to do 10 gallons a week on my tanks but do slip some now and then. Not sure on how long the impurities from tap water would take to get out of a tank but I imagine you would counteract those with the "œnew" water and the other filtration items you mentioned.
