I would like to see if it is possible to calculate some sort of ratio.

Give the following detail:

Total system volume:
DT size:
Sump size:
RO Usage:

My system:
Total system volume: 700L
DT size: 1500 x 600 x 600
Sump size: 1200 x 400 x 400
RO Usage: 50L per week

Total system volume: 560lt
DT size: 1300 X 650 X 550 wl
Sump size: 650 X 530X 300 wl ( 650 X 450 X 100 RO Chamber)
Usage: 25lt in five days on average.
 
difficult
Main tank 750
main sump 250
Remote rock tank 220
Remote DSB 220, (140 about after sand displacement)

Second tank display 220L
sump 150L (80-100L after sand displacement)

Quarantine 90L
Sump 80L

RO usage per week, 150 to 200L
 
My display nano:
Total system volume: 178lt
DT size: 550x500x450deep
Sump size: Dont remember...
Usage: 30lt in seven days on average.
(DT in well ventilated living room)

My main frag tank:
Total system volume: +-160lt
DT size: 600x600x400 deep
Sump size: Dont remember...
Usage: 20lt in Seven days on average.
(frag tank in closed air conditioned room)
 
Dont worry :) each one have different

-Main tank 1.6x0.6x0.6 (0.55)
-main sump 1.2x0.45x0.45(0.30)
-total water: -+ 600L
-35kg LR

RO usage per week, Winter 30L, summer 40L (3 120mm pc fan)

Also perhaps include if a cooling fan is used to cool tank in summer as that would increase usage dramatically...
 
Display 2m x 0.6w x 0.6h
No sump.

Top up RO 25 to 30lt per week.
 
Thanks for those that have responded so far!

Will setup a spreadsheet later today or tomorrow and try to map it.

There are many other variables that will play a factor.
Just tried to keep it simple for some Friday fun.
 
3000 x 1200 x 400, constantly !!!!
1.2 x 60 sump
Prob 60L
 
Interesting thread. Tagging along. New to reefing, still researching but didn't realize evaporation was so high.

In my freshwater it's almost nothing.

Time to add in ato to my research :)
 
What about lighting used? that would be a factor to evaporation. Metal Halides vs LEDs wouldn't that make a big difference?
 
holding tanks
Total system volume: 900L
DT size: 1200x450x450 , 1000x1000x300, 900x320x320, 1500x700x200
Sump size: 1000x1000x300
RO Usage:140L per week
 
Total system size 400L
DT size: 95 x 95 x 50
Sump: 75 x 45 x 30
Ro usage: 30 - 40L per week depending on the weather
 
@dallasg wins.. :tt2:

Actually, it works out to 25 - 30 lt per DT so its average..
