Filtering Tap Water

[treble]

How do I filter water going into my aquarium? I have herd of DO filters, how do they work? Are they mounted inside the aquarium? Thanks for all reaplys.

Do you mean RO filters. If so, no they don't go in your tank, you just hook it up to your water supply. It is a decent filter for the hobby but there are better. Such as a deionizing resin chamber. Even then it is suggested to take your water through a RO filter before deionizing it. But if it's decent water you're looking for then a RO filter alone will work. I personally use the deionizing resin chamber but know that most do not and they too have success.
RO filters filter water through a semi-permeable membrane while deionizing breaks it down even more(to a molecular lever) and ends up giving you one of the purest forms of water you can make.
