I have been using GAC since starting my tank, 25g for my 26 gallon, the recommended (lower) amount provided by RedSea. I replace this on a bi-weekly basis.

I would like to know if there are any downsides to using GAC without an immediate need continuously. I am only aware of two benefits, i.e., improving water clarity and reducing the impact of ZOAs releasing toxins. I assume there is a trace element impact, but not sure about other issues that I might not be aware of. I am testing and dosing trace elements individually.

Similarly, would there be a significant impact if I stopped GAC at this point, or is this not recommended?

Lastly, is the dose I use appropriate or just a manufacturer preference?
