FWIW, in our discussions we might want to distinguish reasonable claims for bubbling the tank with those that verge on ridiculous claims you see on late night television.
IMO, those above fall into that category, and it is quite disappointing to see such comments.
-Clear water, less funk
-Better polyp extension in sps
-More skimmate production
-Less algae on rocks and glass
-Helps treat cyano/diatoms/dinos
-More stable PH at night.
I can say for sure these are the positives I've seen on my tanks.
