EVAPORATION= How much...

[OzoneParkGuy]

Courious as to how much evaporation takes place in your setup. Please list your Tank Size, and Total Water Volume and how often you Top Off your tank and how many gallons you use in a week. Thanks!

I'll start it :spin1:ff

DT=120 TWV=193gal. I top off 2 1/2 times a week @ 25 gallons.:wavehand:

[anthony27]

I top off at around 15 gals a week.

[DrHarryLopez]

DT=220 TWV=375gal. I top off 2 times a week @ 30 gallons

However, if your sump is covered that will greatly reduce your evap rate

[anthony27]

realyyyyyy I always though that covering the sump would make the evap rate go up even more

[afernandez]

60g dt. 25g sump estimate =75/80G TWV

i have a 5gallon bucket (closed) that i re-fill. every 5-6 days (its connected to my ATO)
i have a little project comming soon that would make my 5g to an official 10g reservoir :)

Cool, i wanna see that....

[BIG L A]

DT- 120G, TWV- 130G... I top off 10G about every 5 days.

DT 120 TWV about 180. evap is about 15 gallons a week.

Some stat with the info given
club member/ total water volume/ Weekly water topoff/ % weekly evap
opg 193/45/23%
anthonio 60/15/25%
DHL 375/60/16%
afern 80/5.2/7%
bigla 130/12/9%
dlo 180/15/8%

So with these numbers lets talk about what affects evaporation rate.

I feel that(strictly my own opine) the more splashing that goes on in the sump from flow, causes mi-nute microbubles that pop in the air creating evap. Guess thats why some sumps have traces of saltcreep on the frames.

Too late 4 me to continue, will post 2morrow.

The-D-Lo ... 180Gal ??? Do you have a frag tank also... or what size is your sump then?

[jarrett shark]

5-6gals per day x 7days = 42gals

[DrHarryLopez]

I top off at around 15 gals a week.

5-6gals per day x 7days = 42gals

What is your total water volume?

my sump is a 45 long and i have a 30g fuge. nither are filled to the top so im guessing about 30 in the sump and my DT is 120 minus the rock is probably hold 110g (i dont have much rock i like BIG caves.)
