Water Changes, By The Numbers

This might help us all to understand what it means when we change xx% of water xx times a week. It may not be totally accurate but is close enough to give a really good idea.

Please correct my numbers if you have better ones.

Actually not a find, I worked this out myself but no bragging for me. I like spreadsheets and I use them a lot. After all, if I have a hard copy I don't have to remember so much. :idea:

I have checked and rechecked the numbers and so far it all comes out right. No one find any flaws?

So, does this mean if I do a 10% change 3 times a week, I am effectively doing a 27.10% change weekly?

You got it.
