Ok, let me wrap my head around this....

Mixed media filters are super common.

They Use GAC, Granular Activated Carbon, Silica Sand (various types and grades), pea gravel and periodically back wash them regenerate the filter media.

Are you saying, that if this practice is used GAC never needs replaced?

I know of a couple million gallon exhibits running Ozone,conventional S/F's and zero chemical media...they THRIVE with time backing the success.

From 1995 to present

What is the application for the process you described?

Again, I ask this question to learn, not challenge the assertion!

Thanks in advance
