I never understood why people keep watching this. It’s the same thing Over and over “big tank, big stars”. Which is great for people who are not familiar about fish tanks. I’m and avid saltwater reef enthusiast and I find it more interesting if they shared more details about the equipment used to run the different systems, how they make the tanks (start to finish). There views on the difference between glass and acrylic, fish compatibility, lighting, etc. I am also not impressed with the fake walls and coral, but I also understand the work and maintenance required to maintain a live eco system that I’m sure their clients have no desire to do. Maybe it’s just to much for most people to get into or hold there attention. Regardless, they must be doing something right for having 15 seasons.
