In my experience thus far, a 175 watt bulb seems just a bit too much for
this particular footprint.  I'm having horrible luck with a similar tank
(50 gallon cylinder) and am just about ready to move the 175 elsewhere and
switch to about half that much using power compacts (or the aforementioned
PAR-38 100-watt MH types).  Unfortunately, I just got my indoor water
hyacinth to bloom (that should give you an idea of how high the light is)
so I will wait until after the bloom dies before taking the next serious
