Definitely not IMO. I don’t see how bacteria will outcompete photosynthetic organisms. You don’t see that happening, but even with established rocks that were cured in the dark. Once the lights comes on it’s over for the bacteria. Algae will overdominate. If bacteria is strong enough to outcompete algae, then it’s even more worthless you go out to add them. They should definitely come with corals.Would you put algae problems related to bacteria den?
And even if bacteria does compete, I don’t believe that going out of your way to introduce them is worthwhile. They will come in your corals regardless of whether you want them to or not.
