Evaporation Question?

[bwayne315]

I have a 140 gal cube and then about 50 more gallons in the sump and refugium. It seems as though I am putting 6 or 7 gallons in a week. Is this too much or am I loosing water some where?

Is there a calculator some where to figure out water evaporation?

Thanks
B.

Doesn't seem strange to me...I have a 120 with about 35 gal sump and I am replacing at least that much water a week due to evap, if not more.

Water evaporation is based on lighting intensity, ambient room temperature, tank temperature, how much water surface is exposed to air (glass canopy/wood canopy/no canopy/open sump), number of fans blowing near the exposed surfaces, amount of water agitation at the surface... ..In other words..it'd be a calculator from hell!

...and 6 or 7 gallons a week sounds fine to me.

The humidity level in your house will also make a big difference.

I go threw a gallon a day on my 55 gallon tank... I always top-off everynight before shutting the lights off...

I go through 5 gallons every 4 days on my 100 and thats after adding a 1/4 HP chiller. It was 6 gallons every other day with just fans.

1-2 gallons a day top off for my 180g tank, and 2-3 gallons when i have the lids completely off.

1-1/2 gallons per day in my 92g

I have a 120 gal and 1 - 1.5 gal a day so yours seem normal. Like the others stted the humidity level the temp of your light.
