Most all the bacterias sold in bottles claim results should be seen quickly. I don’t see how waiting a year would be different between bacteria dosed daily or not. Maybe the amount of food the tank could handle would be slightly more but that shouldn’t take a year to happen. I like this topic a lot but I feel like it’s a lot more involved than just adding bacteria. Adding live rock most always ends up helping tanks that are not processing things correctly but bacteria in a bottle, not as much. I think the life that comes on the live rock is invaluable but even then the live rock is just a quick way to start. I have seen many tanks do amazing that were dry rock.
I would bet most people who fail with dry rock fail because they had issues like over feeding, too much filtration, light used incorrectly and things like that which sometimes seems like everything is right and perfect but normally we overlook the simplest of things when searching for what’s wrong. We tend to go straight to complicated. Now I do believe that some dry rock might have more issues than others and might need more treatment before added or more time to cycle properly but it should all work in the end without bottled bacteria supplements.
I have used bacteria when going through rough patches when corals were stressed from something and I have dosed them for a year or so straight and never really seen a difference either way except for maybe clearer water for a bit in the beginning. Sorry but I am kinda just trying to keep the conversation going by being the opposite here, I am no expert, I just have my experience.
Honestly I believe the bacteria produced from using a carbon source is more beneficial to the whole tank than any bottled bacteria. And there is no need to add anything other than the carbon source for success.
