What are you talking about? I don't want salt spray hitting the lights and bubbles in a salt tank is kinda not considered a good aesthetic.
@grey, I went into above kinda why some in the hobby are starting to shy back away from led for corals. Particularly in large tanks where getting full diffused lighting with leds is trickier. (Need tight lenses to penetrate deep but wide to actually get coverage, the cost to put like 6 high end 3 foot units over this thing would be astronomical. (Like @ 5-800/e)
