I had my water tested at a pet store with their fancy-shmancy liquid test just yesterday (last day before a water change), and before a half dozen of the little guys went in. They said my levels are fine. Should I investigate "fine" to make sure fine=zero?
Also thanks for the chemical breakdown, I didn't know you could have different fixes for the various stages. Very cool to know.
Thanks!
Edit: I fully intend on adding a second smaller filter if I happen across one that uses the same media as the ones I already have. Could this replace the bubbler? (10-20g filter)
