Water Evaporation

[BSJF]

I'm moving to San Antonio this next month and I am trying to size my ATO reservoir, so I need to know how much water evaporation people get on your systems? I will have a 150g tank, sump, chiller, MH...

My current 125g setup in Utah uses about 4 gallons a day.

I have a 104g setup and I get about 2.5g evaporation per day. I have a closed canopy.
