There is no doubt that beautiful reef tanks are maintained with the 'bouncy' lighting schedule. The only issue I have with it is when someone claims it is necessary (or even beneficial.) There are so many dynamics involved. I could write a paper on it. Oh, wait, I have.![]()

This involves the maximum amount of light required:Linky?![]()

The 'spikey' method is simply based on the Rapid Light Curves established under different intensities. I've seen a video that made some claims about the benefits. Too bad they weren't true.Thank you for those articles Dana. They are very enlightening (sorry, couldn't resist)
When I view the manufacturer provided spectral graphs for most LED fixtures, they closely resemble what you have observed for LEDs at 8" deep - except that most have a spike centred at 660nm. What I find interesting is that the spectral and DLI graphs for Type 1 seawater at 10 feet deep are quite different with more of a bell curve distribution and much greater intensity from about 470 to 600nm.
Do you have any thoughts on whether it would be beneficial to try and more closely emulate the lighting found at 10 feet in seawater?
As an aside, I have a 28G Zoa/Paly tank illuminated by two AI Primes that are running a variant of the David Saxby 'spikey' schedule. The zoas seem to be thriving with this light, but having never run anything else, I have no idea whether it is better or worse than a non-spikey schedule. I only went with the schedule because if it's good enough for Saxby, it's good enough for me
On my 120G mixed reef I run two cheap Black Box 'full spectrum' lights with manual 2 channel dimming. They're just on/off. The corals in this setup also seem to be thriving.
All this to say that in my limited situation, the spikey bits don't seem to matter.
Is mesmerizing from above. I am gonna buy the hybrid setup this January.Yes, I use my own modified Radion ( 2x Gen3 pros) setting after talking to Mike after he got back from his trip to the UK.
Here is a screenshot of my settings.
