Sure, but some of the best growers out there use very little par in their growth. And I'm not talking about some dude who has a tank in his house, I'm talking about people who rely on growth to feed their family. If high par was the answer, then why are the best of the best running specifically LOW par?
- Vivid aquatics took par readings of their 800g show tank. They're barely getting 250 at the surface. Their average Acro colony is sitting at 175 PAR or so
- WWC runs a modified AB+ setting with their lighting at 60% max, and their lights 2' off the water surface (2 feet, not a typo). That's like 200 PAR or less
- Steve Garret runs a 1300g and 900g outdoor SPS prop tank, and has shaders on his tank to keep par at 400 max at surface of water, average of only 250 PAR or less throughout the tank.
- The people who created the AB+ program only run their SPS at about 175 or less PAR.
Of course I can list just as many who run their lights at 100% and run twice as many fixtures as average. Both groups swear their lighting is the reason why their corals do well. Unfortunately in this hobby, nothing is as simple as black and white. It's all gray buddy![]()
Of course, I understand all the complexities. You aren't telling me anything I don't already know. My point was I didn't want to spent $1700 for a light fixture that gave me 300 PAR max at the surface, that's all. I wanted more options.
