I've been thinking about water changes and I can't really get my head around one little fact.
For example, you change 25% of your water every week, and lose 5% every week by evaporation. That means you have to put 30% of water back into the tank, right? So surely, the minerals etc in your tank would slowly be getting more and more concentrated. So eventually, the water will just get harder and harder, with more and more chlorine or trace elements in it. Have I missed something? Is this right? It just worries me a bit that I might be slowly but surely increasing the levels of toxins in my tank until one day they get too much for the fish and become poisonous.
Can somebody explain this to me please? Am I right?
Thanks
