Trying to weigh out a few things as stand space is a premium and my nano experience was from 20yrs ago. Would you prioritize a larger vessel for additional water volume (essentially double) or a larger ATO if you had to pick one over the other?
Based on the amount of evaporation I’m experiencing on this little thing I’m leaning towards a larger ATO.
Whatever allows you buffer zone to screw up less. I have a 15g ATO tank for this reason
