filtering with brita- do you think it is worth?

[sekiz]

While replacing some percentage of water in the tank do you think filtering the tap water with Brita could be useful? Do you just add tap water without any process?

It depends what you want to achieve. By filtring your water with brita you will reduce Ca and Mg ions. So u will reduce your carbonate hardness.
You can also get rid of the free And bound chlorine, Pb and Cu.
