Evaporation

Hey all just wondering how much evaporation, every one gets each day?

For me i have a 90g with sump and refuge and im feeding about 2 liters a day, just wondring if thats normal and what others are finding with there set ups

 

I have a 55 with a 30 gal sump reg, I go through about 6 gallons a week.

 

75 gallon display, 37g fuge, 50g sump and I go through 10 gallons a week.

 

Now with the heat running i add about 4 gals in a weeks time in my 55 with a sump in the summer it was only about 2 gals a week. and thats with a glass top on the tank.

 

55 gallon about 4 gallon a week

 

so basically most go through about 15- 20 gallons per week.

As it is winter time here now i have noticed a huge jump in how much i put in

 

120 about 12-14 gallons a week.

 

125 gal and about 10 gal a week

 

15Gish per week

 

90g tank with a 20g S/F. About 8g/wk
