Typical evaporation Rate?

[customclimates]

Since going to my 120 from a 90 a lot has changed in my equipment as well. I know have 250?s with a blue wave 7. Evaporation rate seems to be a lot more than the 90. What is everyone?s typical evaporation rate for this time of year? I understand a lot of factors come into play for this question. Just curious?.

I have a 125 gal reef with mh lights and it evaporates around 1.5 gal per day.

I found that the biggest factor for evaporation was whether I ran a fan over my basement sump. I had a 65 w/ 3x175w MH, and the evap rate was a couple gallons per day. Allowed for lots of kalk dosing.

I'm at around 2-3 gallons a day

I went from a gallon to about 2 or 3 per day... Just seemed like a big jump. Keep freaking out checking the rug for damp spots! LOL

The size of the surface area has a lot to do with how much you will evaporate. Also, the turbulence of the surface make a big difference too.

What? Meaning that if you have alot of surface area, you'll have more evapaoration? If you have a fan? Will that lead to more or less evaporation?

Added four Oceanflo mods too!

You've seen my system. I evaporate about 3 gals now and around 5 gals in the warmer weather.

Any surface turbulence will add to the evaporation as will a fan.

thanks... I look forward to alot of adding water...

about 3 a day here, auto top-off is a great thing

3 + per day here on a 120. Lots of fan on the surface though.

We evap. about 3 per day all year long.

[spivack]

about 2.5 per day here.

 

[Calciumbuf]

6-7 on an average day

 

[ron168]

about 2 a day for my 120.

What has anyone done to try to minimize evaporation? tips/tricks of the hobby?

Personally I try to evaporate as much as I can, this helps a ton with keeping tank temps from getting too high. Not such an issue now, but in the summer it makes a big difference.

If you want to minimize evap, you could cover (blocking some light in the process) or partially cover the tank. Also covering the sump would help to reduce evap.

I don't try to stop the evaporation either. In the winter it helps put moisture back into the air which the heating system removes. In the summer I run stand up fans on my basement sump and tanks to help keep the tank temp under control. I just use an auto top off.
