What is the lumen output of your tubes? You could get away with only
2 tubes by using very efficient ones, like Ultra-Trilux. A 30 W of
these puts out 1880 lumens X 2= 3760, that's 30 lumens/liter. IMO that
should be enough esp since you have only 2" of clearance inbetween the tubes
and the water level. Is your canopy equiped with a good reflector ?

I would be very interested in how to use a 2 bulb electronic ballast
with only one tube, too. Alternatively, you could get a single tube
ballast for the third tube. I haven't look for 30 W, but my local Home
Depot sells a 24 W single tube Advance magnetic ballast for $8.
