The biggest difference? I think it's the temp control. I still have it at home, and its temp is close to 84 (the room temp set to 77.) If I take it to my "freezing" work place (the thermostat setting keeps migrating toward 65 for some reason from 75), I suppose it will be lower for sure. I suspect that its own tiny power filter is actually adding some heat to the water, too.
The maintenance is relatively simple so far. I add some top off water in the morning using a small beaker. I change 10 - 15% of water every week (2 cups.)
I just can't stick my hand in the tank for any reason. I have to use a long pair of tweezers to pick up or rearrange frags. I use a smallest mag float to clean the walls, but if I am not careful, I bump into rocks and change the landscape. I rely heavily on tiny livestock to the cleaning for me. I have a few collonista snails and a few micro brittle stars for that.
I do not know if I recommend a one gallon tank to anyone. I'd go a little larger.
