Your comment makes me wonder.wondering if current existing and established bacteria would out compete new bacteria strains too
I've used ZeoVit Cyano Clean Bacteria, at least twice.
It works to speed up a Cyano Outbreak cycle, thus ending Cyano problem.
Their product does say the way it works, is the Cyano Clean Bacteria outcompetes the CYANO BACTERIA.
So my point is, when I put in the Cyano Clean Bacteria, did it out compete the other good Bacteria in my System? It's probably a good strain of Bacteria and stronger to out compete Cyano-Bacteria, but makes me wonder about the state of Bacteria Diversity in my Tank.
