Solar intensity

[Shadows Reef]

Does anyone know where to find information about the solar intensity of the coral reefs throughout the year as the seasons change the amount of light the corals get is important to coral spawning and I’m trying to spawn some colonies in my tank with the help of apex’s season table, simulating sun rise and set times, water temperature throughout the year, with the moon light simulator. The only piece of the puzzle I’m missing is solar intensity throughout the year.

I posted a video just last week showing par of 1800+ in my outdoor frag tanks. Good luck with trying to match the intensity in your tank.

Check on youtube under o2manyfish - The video with the PAR values is titled Frag tank at 108 degrees.

Well as long as I can simulate the intensity differences as the seasons change I should be on track to trigger a spawn event. I don’t quite need to match the actual solar output as par will be different for corals at various depths but the values of the changes in intensity is important to me.

BRSTV has a MACNA presentation by Richard Ross. I think the graph or spreadsheet your looking for is there.

Thank you I just saw the chart that helps out allot I’m seeing if I can find a more detailed one.
But at least this way I can see when to set my highest and lowest intensity. It’s interesting how the intensity it highest in summer then lowest in spring and fall and 2nd highest in winter.

It's going to depend highly on the lattitude of the natural reef you are wanting to model.

I found this which is what Richard Ross was talking about with his coral spawning: https://onlinelibrary.wiley.com/doi/full/10.1002/ece3.3538

I think you just need to pick high and low seasonal intensity and just stick with it. The corals should adapt and respond.
