Evaporation rates

[MR.BEE]

Hey recently started my IM 40 fusion and I’m curious does everyone else water in the sump evaporate fast.

 

[Auquanut]

I lose over a gallon a day to evaporation in my 125. Relative humidity plays a big role in how much is evaporated.

And welcome to R2R!

I lose more than half a gallon everyday in my 75 gallon, but I have metal halides over my tank, which get very hot, so I’m sure that evaporates water a little faster.

My open top 150 with 50 gal sump evaps 1.5 to 2 gal a day. My 58 with glass lid , 10 gal sump evaps 2 gal a week.

I lose 2gallons a day in my 125. Yes a lot. But I have open top and a lot of ventilation

That's a given with any tank and why they have ATO systems. Those were a godsend over the old days of trying to keep up carrying and adding tipoff water. Winter/house heat is the worst but AC is close and of course you will always have some evaporation. I couldn't deal with my 200 w/o an ATO.

My evaporation has been through the roof lately. Even with the wet spring weather I'm going through a liter a week in my 2.5gal. I think the city is putting less molecules in my water.

!!! Welcome to R2R !!! Evaporation volume will occur depending on a few factors like, room temperature, ventilation etc. Sometimes is more at night then at day time. That's why an ATO will keep that in check.

I run the same tank with a hydra 32 over it. Currently running an ato and I have to replace my 5 gallons every 12 days or so.

 

[Alarmguy66]

Same tank here as well, around a quart a day. The thing with this tank is that it starts throwing bubbles at that point. ATO is on the way to handle that situation.

I have a kessil 160blue

Here’s my IM 40 fusion

 

[Auquanut]

Awesome scape!

 

[MR.BEE]

Thanks man it’s a process I see that.

 

[Shorething]

My 220 gallon eats 10 gallons of ato a week

 

[Dragon174]

My 120 goes through 5 gallons a week if not a little more. I also have tops on my tank which helps with the evap.

 

[NormanB]

My open top 75 with a 55 sump evaporates about 1 gallon a day.

 

[Billdogg]

Between 1 and 3 gallons a day depending on the humidity for my 120.

I have the same tank and I average 1.5 - 2 quarts per day.

Room temperature delta and relative humidity play a huge roll. My tank (180g topless) can go from 2-3 gallons a day during peak summer where the AC is set to 76-77 and runs 6-8 hours a day to barely any in the fall when the inside temp is 72-74
