1 gallon evaporation a day in a 46 gallon tank too much? MH 2.5" from water.

I am running open top on my tank and have my metal halide light 2.5" from the water, I noticed I evaporate almost a gallon of water everyday from my 46 gallon tank, is this too high a rate of evaporation?

Is evaporation as bad with t5's as it is with metal halides?
