The Zooxanthellae present in most Corals produce a massive percentage of the Corals food I think and I kind of draw the analogy to plants in that Zooxanthellae are photosynthesizers and produce food for the coral through photosynthesis, in turn the coral grows. I believe if you provide the coral with the perfect lighting and spectrum to have the Zooxanthella thrive you could have dramatic results. What interested me most about the hobby to begin with is the lighting people use to grow coral because it's way different to say a metal halide or HPS light which are commonly used in horticulture to grow plants. It still doesn't make sense to me that nobody uses them for the Marine Aquarium hobby to grow Coral if everyone uses them to grow plants? I assume for power or budgeting reasons but I don't think any lighting mimics natural light better than a combination of Metal Halide and High Pressure Sodium lights, it is literally a perfect imitation of natural light with the perfect combination and it's comparably as expensive as regular Reef lighting and way cheaper than any pro stuff like Radeon.Run T4s with radions. The radions are on from 8:30 to 7:30pm with program ram-ups the T4s are on for 3 1/2 hours mid day.
try to mimic life near the equator.
I read in another post that there’s published literature that says corals benefit from an intense three hour light cycle. Is there any back up to this - could not find the article
