After 19 years in the aquarium trade, I’ve seen so many things come and go. LED lighting has arrived with promises, how long lasting they are, which hasn’t tested yet. Manufacturers are producing lighting to make money not light your tank the best. My suggestions may be old fashioned but they have been the best and simplest. Serious coral tank reefers still use metal halide / VHO. Plenums de-nitrate unlike deep sand beds. I do believe in new innovations, garlic as ick preventative, is a great one. KISS still works. (keep it simple stupid).
