I believe this is true for different strains of bacteria whether it’s anaerobic or aerobic bacteria. I believe Microbacter clean and vibrant are both anaerobic bacteria or ”dentifying” bacteria.
The only problem with denitrifying bacteria is that it's really hard for them to populate in our reef tanks I believe that's why we have to add it every week or every other week.
Dr Tim’s one and only is fantastic a i’ve used it many times I believe that is aerobic or ”nitrifying” bacteria.
I didn't use it this time as I wanted to try the dry rock fishless cycle kit from brightwell which came with ammonia, microbacter start XLM, and MicroBacter clean(how I got in the dilemma I'm in)
When it came time to use the microbacter clean I instead used vibrant because I believe they are the same just lots of speculation that vibrant is better and I'll like to find out myself.
