The Berlin Method that I use is this formula:

1. 1.5 pounds of live rock per gallon. In my case about 45 lbs of rock.
2. Strong protein skimming. In my case, CPR's Dual BacPak which runs 2 skimmers and is rated for a 100 gallon tank (with the bio-media removed. I can explain why if you'd like me to).
