    I am a supervisor of a wastewater plant. We use nitrification, denitrification in aerobic systems and use anaerobic systems for the destruction of organics. Phosphate and Nitrate is consumed by facultative bacteria not anaerobic bacteria. Facultative bacteria can switch for a simple explanation...

    Guys, I was thinking about this earlier and would like to start a discussion about it: We all know that converting Nitrate to N2 requires anerobic bacteria located deep inside live rock where there is little water movement hence little oxygen (anerobic enviroment). I'm wondering if larger...

    Ok i know this is a highly debatable topic, but i want a little clarity on the theory, not wether or not it is a good idea. refugiums are supposed to help keep nitrates in check in most applications right? so my thought is that there should be a very low amount of flow in the refugium. this...
