Led build questionsPosted:

In my experience, imported, black box LED lights are just not the right spectrum. Some seem to grow hair algae better than anything. For sure, coral just don't grow well under them. If it were me, before wasting one more minute on it, I'd toss it in the trash. Then I'd save up and get some decent LED's like the models of the last few years made by Aqua Illumination, Kessil and Radion.
Recently came across a Red Sea 250 where the hobbyist removed two of the six t5's and put a LED light strip in their place. They said it was to get more shimmer. As I looked at those LED's there was no brilliance to them. I asked but the hobbyist had no idea what wattage LED they were. In my opinion, they were putting out less light energy than useless 1 watt LED's. It was clear to me that the hobbyist had compromised the effectiveness of their light fixture. The tank was under illuminated. No wonder they'd had issues with algae overgrowth and coral survival, the remaining four t5 lights had not been replaced in over two years.
The next meeting is going to be excellent on this very topic. It will be a discussion led by a person extremely familiar with the physics of light. I'm imagine there will be much discussion regarding which LED's are effective, which should be tossed in the trash and why.
Good luck and Aloha,Mark
