How much weekly top off estimate for evaporation for hoodless 34 G. Red Sea All in One?

If I remove my hood on my 34 G. Red Sea cube AIO, what's your guess of how much water will evaporate per week?  Curious how much RODI I'd go through weekly?

it'll depend a little bit on airflow above the surface, surface agitation, and general humidity of the area.

my 75g evaporates ~5g in 3 days. so i'm assuming it'd be about half that so maybe around 0.8-1.0g i'd guess.

We go through a little over a gallon a week on our 17gallon ADA 60P. 
 

On our newest build, an IM 40Long, I’m going through 2.5-3 gallons a week. 
 

We live in a dry climate (Phoenix) and run a bit of flow. (There’s no replacement for displacement, yo!) So we might be a bit higher than average.

I'll guess the "most" you would be likely to see is about 5 gallons per week....but actual usage is likely to vary quite a bit, at least with the seasons (eg HVAC running a lot, or not).
