How much evaporation do you get?

[Ferrell]

It’s been a while since I set up and I remember topping off frequently but just curious what size DT/sump and how much you loose every day. I’ll go first:
4’ - 75 gallon DT WITH 30 gallon sump (20 gallons H20)
Loosing about 1 gallon a day
ATK in the mail

I’ve just had the tank up and running for a week, tweaking the system before I start cycling. Dump 2 qts in the morning and two at night. Just curious what everyone else does

ATO for sure, especially with corals...
I have everything covered, so that reduces evap.
But in the summer, it’s about an 1/8th of a gallon per day.
Winter, if heat is on, it’s much more...

I have an IM 25 that goes through 3-5 gallons a week depending on the time of year.

81 gallon Vater volume about a 1.25 gallons pre day. DT is 72 gallons

 

[Yuki Rihwa]

Cool season like Spring/Fall/Winter I lost 1/2 gallon a day.
Summer 1 gallon a day.
I have no sump/skimmer just open top 50G tank.

I have basically the same setup as you, 75G DT with a 30G sump that isn't full. I lose about 1 gallon a day too, it was slower during the summer, but now that it's getting cold in DE its going up. However I just added a wrasse to the DT, so I put glass lids on the top and it's reduced my loss by probably 1/2.

110 gallon stock tank in a greenhouse. About 6 gallons per week depending on the ambient temperature.

I have a 90 total 75 display. I go thru about a gallon a day.

 

[AdamNC]

29 gallon with 20 gallons volume and I go through about 5 gallons every 2 weeks.

In the summer 10g ATO reservoir lasts about ten to twelve days, but in winter only about seven or eight. I have about 70g water volume.

Most people evaporate something like 1-3% of the total water volume daily.

220DT, 40gal sump, 75gal fuge. I haven't measured it exactly yet but it's in the neighborhood of 1.5-2gal per day.

60gal DT, 20gal sump. .5-.75gal per day.

90gal DT with 30gal sump and go through 5 gallons every 3 days. I live in Colorado though so NO humidity.

120 dt, 40 sump, and 40 frag tank. I am losing a gallon or so a day.

150 gallon tank tank 55 gallon sump it's ruffly 6 gallons a week my ato container is a 6 gallon bucket it'll last me anywhere from 5 to 7 days

 

[owenmck1]

40 gallon display and roughly 20 gallon sump I lose 3/4 to 1 gallon a day

 

[Raptor72]

My 125 would go through my 15 gallon can weekly back in Az. I haven’t set up here to know yet.

I have a 32G display with ~15 gallon sump and my ATO container is just over 8 Gallons, lasts just over a week so approximately 3/4-1 Gallon per day
