Taking advice based on the look of a persons tank is not something I would recommend. I always find that it is good to absorb advice/experiences but then I take that information to do research and form my own opinion. Going way back to the time I worked at an LFS I could not count the number of times I worked with customers that took someone's advice without understanding the why or questioning if it was the right thing to do. In some cases I would hear that a person had a nice looking tank so they thought they knew what they were doing. The challenge is that there are too many variables in this hobby that can be factors in the success or failure of an aquarium based on implementing changes that were advised. 10 reef tanks can be setup the same exact way by 10 people following the same advice and all the tanks will turn out different over time with different levels of "success/failure" One of the reasons I enjoy this hobby is the challenge of maintaining reef tanks knowing that it is not luck and requires me to constantly learn and grow my knowledge.
