Why should I do water changes?

[Pistondog]

Yeah that's what I was trying to say towards the last part of my post. Thanks for clearing it up.

@Timfish said It more precisely.

I do water changes to remove some of the undesirable things that get added to the tank. For instance I will sometimes dose potassium nitrate and without water changes my potassium levels in the tank would just continously raise higher and higher.

Unless you get things that consume the amount of potassium you are adding.

This is always a fun debate. So many opinions on either side.
