Fritz, Watch your inverts when you raise that mag. My starfish got sluggish and I am not sure, but I think I started losing snails (hard to count). Emeralds made it through just fine. I didn't have many hermits, but they were fine too. The cleaner shrimp seemed to be ok too. I never got my mag higher than 1600, however....
Serpent starfish I found upside down on the sand one day, so I plucked it out and dropped it in the other tank. I'm just saying, keep an eye out. I was watching cuz I found on the internet, so I didn't know if it was true, that raising the mag had wiped out somene's inverts..
High mag levels for some reasons makes snails loose their grip. You'll likely have to take them out while doing the high mag. (if you go really high, 1500-1600 they seem to stick, 1700+ not so much)
I had good luck using both tech M and BRS.
