Your basically removing all dissolved minerals / buffers that are in the water.
If your trying to maintain a soft water tank ... RO/DI's the way to go if your tap is naturally hardwater. Problem with RO water is it's susceptible to pH swings since it lacks buffers that help stabilize pH.
2: Is there such thing as over filtration. For example if i put a Fluval 405 canister filter on a 50 gallon tank is that too much?
Yes and No ... One or even two Fluval 405's in a 50 gal is no big deal, but having say two FX5's in a 55 just becomes unnecessary. While you would have good 2 filters, you may not necessarily get any more effective filtration ... there's only so much BB that a tank's bio-load can support and adding more filters won't cause more BB to grow.
