This is a rare answer from a guy who usually gives precise numbers with back up papers for reefing questions.I don’t know how big of a part, but wild guess, 10%.
More unusual/more interesting organism availability, 30%
Better flow tools: 20%.
Better lighting: 5-10%.
Better foods: 5%.
Better informed aquarists: 10%.
Other: 15-20%
Just wild guess opinion…
