Heres my best way to explain f-stop, shutter speed and iso
F-stop: largest opening of the lens. The smaller the number, the wider the opening.
At wide open am f2.8 allows more light than an f5.6
Shutter speed: how quickly the shutter closes.
iso...dont know how to explain it. But basically the higher the number, the more sensitive to light the sensor is
Im not a pro...im a bit above average amateur or so. But thats my best ay explaining it

it's a bit more complicated than that, because each one impacts the other.
more specific to reef photography though, one needs to be more concerned about f-stop, not just for the amount of light taken in, but also because f-stop dictates DoF (depth of field). this is especially true with macro photography, because the DOF is VERY shallow.
you would need to decrease your aperture (increase the f-stop), in order to get a deeper DoF, which results in needing more light, which will mean either slowing down the shutter (which takes hand holding shots out of the equation), or increasing the ISO (increased noise from the photo).
of course, there's the alternative - flash.

Oh I agree wholeheartedly. I simply tried to provide a simple explanation of what each does. How they're related is best left to an in-person explanation.
