No offense - unless you have any evidence for these claims, why should anyone believe you?
1. I agree with you about not dosing medications/antibiotics into a display tank. A hospital tank/individual set up is best.
2. I have no experience with MB7
3. I have had great experience with vibrant - and it works well - with certain caveats.
4. You can indeed set up a tank immediately adding whatever you want and be successful with Fritz turbo start.
3 and 4 are not just my opinions - there are hundreds of posts documenting this. Do you think that LFS who start up a store - cycle their tanks for 6 weeks, hoping, that it will look good? When people take tanks to Aquarium shows, do you think they set them up in the auditorium for 6 months?
I guess I would like to hear your rationale scientifically 'why', you can't add live rock to a tank, add bacteria, and not have a functioning reef? PS - the adage 'nothing good happens quickly in this hobby' is not an allowed response

. PS - I'm not trying to be overly critical, only asking for evidence. PPS. I'm also in agreement with you that adding unnecessary bacteria, elements, etc is overdone in this hobby, BUT - when needed these products work quite well (the products you said don't work above)
