I've been away from the hobby for a few years but am in the planning stages for a 75g I'm going to set up this fall. Back when I had my big tanks, I used both Aqua Illumination and Kessil LED fixtures and liked both very much. They are expensive though, so I thought I'd see if there are any other brands/fixtures out there that hold up and perform well. Someone recommended the Fluval Smart LED 3.0. I would prefer to have a fixture that rests on top of the tank rather than one that hangs from the ceiling, but as I recall from several years ago, the LED fixtures that sat on the tank tended to be weak, and didn't sparkle and shimmer like the AI or Kessil lights. Can anyone share experience with or suggestions for other fixtures?
