Almost 5 Gallon a week evaporation!

That would depend on how much you run your AC. That lowers humidity inside and increases evaporation. My top-off drops to 1 quart every 2 days without AC.

 

I do about a gallon or more a day in my 90. Top off has been a pain in the butt. I will be setting up an ATO this weekend ;D.

Running A/C does dry out the air, and I would think contribute to evaporation. Once A/C season is over, it may slow rate of evaporation.

 

I probably top off just under a gallon a day, on a 65.

 

Dang it Golden Rhino! You beat me to it. ;D That's what I get for trying to work and post.

 

When the 75 g system with sump was up and running, we topped off 4-5 gallons a week. Now with the 120 g system up...it is connected to a 75g DI tank which is topped up nightly from the RO system...so, I don't rightly know how much I'm using...

 

i here ya 12 to 15 gal. a week on my set up.

 

I refilll my 5 gallon Auto top off button 2 to 3 times a week on my 75, so that seems kinda low to me.

 

depends on tank placement, how dry the air is in your house? forced hot air/ and a/c will dry the air out. Also equipment will vary some lights will burn off more water than others. Open top tanks pumps and surface agitation will all contribute to evaporation. So yes tanks with very similar conditions will loose more water to evaporation in a dry climate vs a wet climate but that's not the only contributing factor.

 

Im somewhere around 10 gallons every 5 days or so with my 180. my 75 was a gallon a day.

 

for my 90 , im 5 gals every 2 days.
