This crap just gets re-cycled every few years or so. In the mid eighties I got involved in building reef systems. Many hard bound books and other materials where purchased and studied. Same old same old was addressed back then. And I can clearly remember even earlier on, reading news paper articles or hearing on the moron box news forecasts as how some areas of the Pacific for instance where loosing their reef systems due to acidification. It all is bull shit. to the nth degree.

“Although none of these threats has ever become manifest as a serious impact and all of the millions of dollars in research has never found any effective solution for anything, the charade never seems to lose credibility or support.”
That about sums up the last three decades in climate science.
Coral Reefs are major work and very expensive. I had two used Metal Halide street lamps, a used Protein Skimmer and tried to go cheap.
My advice - if you want to go this way is to go for the best and be prepared for a lot of work. Folks will go ahhhh, and ohhhh when they see it, but you will be fighting fireworms and parasites and chemical problems weekly.
Have heard about the new LED lights which are probably worth it. The Metal Halides evaporated the water like crazy and had problems in the summer with temperatures.
Good luck to anyone who tries it.
