After watching a bunch of his videos my "conclusion" is inconclusive.

IR has mixed effects depending on species and none included aquatics.
Other studies showed benefits only
when light intensities reached photosaturation .
That may gave some benefit to aquatics that have low par saturation points
Then again those low points are still high compared to common light output .
There was also some that concluded you inly git vebefits by applying fr 15 min before and ir 15 min at the end if the photoperiod.
Not sure where that came from though
Fr has been known to initiate flowering (do we need that?) and to stretch plants
Another unknown is the aquatic environment is backwards to the terrestrial one w/ high blue ratio signalling "shade". Reds being attenuated at even modest depths.
Point is nothing found us really currently studied in nor applied to aquatics.
Think of the differences in form of emergents which must involve a massive reconfiguration of biosystems (personal thought).
As to leds there are "Emerson effect" strips you can buy
Bud Booster Emerson Effect Sun Board 48 LED Strip 660nm 730nm IR Quantum Grow
$20.67/eaFree Shipping
Or 730nm diodes.
660's tail into ir though believe it is under like 1%
Those " full spectrum" blue plus red phosphor diodes seem to tail in more than the 660s do. At least on paper.
I run pure 660 for a period during initial lights on and pure 660 prior to lights off. Mostly because I like it.
