I've found that using low media sample of 1 often produces adequate
results, where 2 or 3 give blotchy results, not looking decent until
samples ot 20...and sample of 1 is a lot quicker ;)
also I habitually use confidence of 0.0001 and variance of 1.

to get underwater sun-beams, make a large hollow box, place camera
within.  place a light source external to the box, put a sphere with
a turbulent pattern of your choice varying from opaque to transmit 1
around that light.  this gives a nice texture on the surface of the
water, and beams of light.  for water colour, try a fade distance
appropriate to scene, and a blue emission colour.
