How much RODI does your ATO use?

[LadyTang2]

My 120 with 40 breeder sump uses 1 gallon a day in the winter and 2 gallons a day in the summer, give or take.
I run a 10" fan on the sump in the summer which accounts for the doubling.
No heater in the summer and a 150 watt in the winter.
Tank runs 79-80°.

what part of the country are you in? Are you heating the place in winter?

Open top tank and sump. Average about 5% of total water volume per week (a little more in summer and a little less in winter).

surprised by less in winter, what state are you in?

I was thinking, heating in winter would cause more evaporation as it makes air dry

A 10g 20g and 20g tank. I use about 2g of rodi each in a week to week and a half

Colorado, it's pretty dry here most of the time. Increase in summer is due to using a fan for cooling. I also run a humidifier on the furnace in winter...
