Top-Off for Nano

[cbianco]

Here's a good article cbianco put together. I started doing this ~month ago and it acts as my top off. Of course I do my weekly water changes. I go through ~1 (3liter) bottle a week in my 12g.

Here is the link to the article: http://www.maast.org/index.php?name=...ic&t=23553 .
