You might want to look into an automated top off system. Works great for me, I have a 24 gallon storage bin that I fill up with fresh top off water and it sits inconspicuosly in the corner next to my tank with an airline hose run from it to my sump. The setup I have will keep my tank toped off at a consistent level for up to 2 weeks at a time. For my setup I got a $80 controller and sensor system and a $10 mini pump.
Personally I didn't find my 30 any more difficult than my 50 I have now...
