185 + 48 gallon sump.

I use glass covers on the DT. Between the fuge and the skimmer I evap only about 1/2 gallon per day in the dryest part of the year.

Time for ATO.

Almost certainl to buy Tunze based on reviews. What I can't figure out is if I want the osomolator 3 or the nano?

I realize the nano is only suggested for up to 65.gallons but I have a much lower evap rate than most 200+ gallon systems.

Price is not my main concern....getting the right one is. Will the ull size O3 wind up running for only seconds before shutting off? ....or, conversely, will the nano struggle?

I can't find specific gallon per hour ratings on the two pumps so asking for anyone with real world experience to offer some advice.
 
I would still get the Osmolator 3 just to be on the safe side!
 
You will want the Osmolator 3 with the built in safety and redundancy it brings
