How much evaporation

[Briko03]

Just curious how much evaporation I should expect from a 72g bow with a 30g sump? I know this is tricky to get specific so estimates would be helpful. I have a 150w mh.

it will depend on if you have a glass top to hinder evaporation;
if you have additional heat on or A/C in the space;
how much surface movement;
too many things to evaluate
I have a small tank w/a glass top so I don't loose more than 2-3 gal/week

I lose about the same in my 55 gal with an open top.

I would guess @ 5 gallons a week . Depends on a lot factors as others have stated . Fans , AC in room . Wet skimming , How much u stick ur hands in the tank ....

I add about a gallon a day in my 90g.

I lose about 2.5 to 3 gallons a day... depending on the weather, as i dont lose as much when its humid, and numerous other things...

yep.. 3 gal a day if you run your hailides for more than 6hrs bud

I Add 3 gal a day with ease

Great question I was going to ask this. I have been at a gallon a day and thought it may have been excessive.

Yea, i was concerned there was something else going on but it appears as thou my rate of evaporation is reasonable.

60g cube 150w MH - I lose about 1gpd, just setup an ATO
