First the only thing 'wrong' with distilled water for the aquarium is that it is too pure, If minerals are added and pH is adjusted, it is just fine (same as RO, DI, RO/DI water).

I believe Brita is pretty much just a carbon filter which removes many impurities and just like using activated carbon in the aquarium filter, it is just fine.

Agreed. We have one too and that iss all the filters are. Just carbon.
