Circulation, running pumps at night

I have a filterless tank.  I have plugged the pump into the light switch.
There doesn't seem to be any problem with CO2 accumulation.  The fish are
all normal in the AM; anyhow I am pretty far below the fish inch to surface
area ratios suggested in most books.  Any reason why there'd be a problem
with this?
