ATO Resevoirs & Evaporation?

Planning my ATO resevoir. I don't think it will fit in my stand and the tank is in a living room, so I can't exactly just sit it next to the tank.
What's everyone else using?

Also, any idea what kind of volume I'll need to keep a 200 gal + 50 gal sump topped off?

Thanks!

 

Here's how I'm doing it.

For a 250G system I'd anticipate a minimum of a couple gallons per day.

 

Interesting write up, thanks for the info. Right now I wasn't planning on having my RO/DI unit in the same area. I'll have to research that a little more and see if that's something I want to reconsider.

Thanks!

 

You're welcome, tingleyl. My RO/DI unit is in my laundry area. I ran the tubing through a closet, a bedroom, and into the living room. It took considerable work; but I think it was worth it.

 

My RO/DI and 23 gallon ATO storage are in my garage while my 100G display is in my dining room. I use a peristaltic pump to pull the water from the garage to the tank and ran the line through two walls and behind some baseboard moulding so its hidden.
