Water Change Rate

even with low clorine levels it would be inexpensive and easy to add a simple carbon filter system to it. just to be safe.. i would. can help with contaminate removal too.

Agreed, water company have a habit of changing things for seemingly no reason. Whilst our PH is always high KH rapidly changes.

Bump for a great link.

I just dug it up again to get a better idea of how turnover is.
Some other math is straight forward and can/should be done by hand, but with this I enjoy the laziness of just typing it into the blanks.

Thanks again for the link
