Thanks for the fair and honest feedback. It's important to really consider what we share.
In the end, you are right there are no peer-reviewed studies that show any cycling method works best and there probably never will be. This is particularly true when referring not just an ammonia cycle but also the mindset of just getting a tank ready to support SPS corals and avoid some undesirable pests. As with all the information we share I would encourage everyone to take the bits that are valuable and leave the rest.
That said, because of the lack of peer-reviewed studies all we can go off of are our own experiences and those we know and trust. All you are seeing here is the combined experiences of the BRS and WWC team, all the individuals that work here as well all those we know and have talked to. This is hundreds to thousands of tanks and experiances but I still can't guarantee we are right, in fact, we often learn many things over the years and find there are even better ways to do things as time goes on. In this case, it has been our collective experience that longer cycle times produce better results. To a lesser degree, the available bacteria products will likely help many reefers with components of the cycle. In the end, it is difficult to prove anything definitively does anything in this hobby but I can say after the hybrid series is over we will all watch the tanks, share how they do and I want to circle back with BRSTV investigates to start learning why and how certain approaches of the method work or don't. The bacteria claims are one of the more interesting.
I will never blame anyone for saying "those guys are just trying to sell stuff" because we are a business that sells stuff

That said the approach that sells "the most stuff" is one that helps people be the most successful with their reef tanks, it is not suggesting snake oil or magic elixirs

I can only hope that comes through in what we do. I can't garuntee we are always right because we certainly aren't but I can guarantee the goal is always the most successful reef tanks possible.
