Personally I think that is a waste of money. It's not hard to pour a few 100 mL of water into the tank every couple days. If you can't handle that for maintenance then a nano is probably not for you.
Personally I don't think it's a waste of money. With 32W running 8 hrs a day there's a lot more than 100mL of evaporation, plus I have a job that requires traveling on the weekends (Fri-Sun). ATO system would safe guard drastic evaporation. To be honest, I never asked what you thought of me getting an ATO but thanks for your input.
Anyways, a buddy @ the LFS told me about this site, they carry ATO for nano tanks
for $45. Probably invest in it next week.
