I too would be interested to see what the more experienced say. I am setting up a 40 Breeder Tank in the very near future w/ 1.5-2lbs/gallon Live Rock and a CPR R2 Bak Pak for Protein Skimmer and Deep Sand Bed...and NO
SUMP OR REFUGIUM planned. I will be having 3 powerheads for water circulation (3 x 240g/hr = 720g/hr = Water Turnover of 18 times per hour (plus what comes from the Skimmer)).
I was under the impression 1.5-2 lbs/gallon Live Rock and water turnover of 10-15 times/hr is was is needed for FOWLR
or Reef Tank setup.
