top off water

[alrmc4]

i am putting in about 48 ounces of top off water (ro) a day is that normal?

ya depending on where your at and if there is a cover to your tank, it's posibal to evaporate a gallon or more daily.

and the size of the tank.....we replace 5 gallons daily. You want to encourage
evaporation.

 

[alrmc4]

thanks both glad it is a good thing

 

[ReefRaff]

we replace 5 gallons daily.

WOW! you must have a large surface area?

 

[Hara]

large surface area that is completely uncovered and has two, 10 inch fans blowing across the top, plus the sump...bowfronts have just a little bit bigger footprint (Ithink)

Why do we want to encourage evaporation?

 

[Hara]

it helps with cooling for one thing.

180 g reef=3 1/2-4 gal per day
20 high reef w/sump=1 1/2 gpd
20 long coral tanks=2gpd
Thats about what the tanks I have average.
My puffer tank has a glass top and NO lighting. Never have to add any water to it between water changes...it drops maybe 1/4" in two weeks.

More gas exchange aswell, I get barely any evap, but the little i do get makes an auto top off the next thing on my list.
