Don't know how to do that little Quote box, but ScorpiNo posted "Keep your PH up as Ammonia is more toxic at a lower PH". BACKWARDS. pH is the driving force pushing the ammonia/ammonium equilibrium back and forth. Higher the pH, any ammonia present will be shifted toward the toxic free ammonia as a precentage of total ammonia. This is the main reason marine aquariums take longer to populate and why they used to take longer to establish and cycle.
