Just remember also that the more evaporation your tank has the more
important the water changes are....

If you just keep topping up you are concentrating the dissolved minerals,
calcium etc......as it is only "pure" water that evaporates.

you could get an early case of Old Tank Syndrome if you don't keep up the
water changes...
