Welcome to reefforum Dr.Hovanec !
I believe I ran into you at MACNA in Boston a couple of years ago before you wrote your articles in advanced aquarist questioning Ron Shimek and his toxic findings in some ASW mixes. Michael Del Prete is still very upset at you
Also adding to the questions João has presented, are some/all of these bacteria already present in the aquarium and does adding a carbon source via {Vodka, vinegar, sugar, zeovit, prodibio etc.} just increase their levels ? Can these bacteria be exported effectively via skimming ? What are the potential problems if there's a mass dieoff of these bacteria because of lack of "food" ?
