Evaporation poll. Read first post and then do math please.

[skinz78]

I am wondering what you all see in dayly evaporation from your tanks. For the purpose of this poll I am going to make the choices in US cups. I want to know how many cups per day your tank evaporates. When you vote please respond with a message on how many gallons youre total system is.

Lets use a ten gallon comparison for this. So lets take my tank for instance. It is approx 90 gallons total volume and I have roughly a evaporation rate of 2 gallons per day. So if I took the value of 16 cups per 1 US gallon and times that by two I get 32 cups "16 x 2 = 32 cups per day". Then I want to find the amount of evap of 10 gallons of my tank water. So I need to take my total water volume of 90 gallons and divide by 10 gallons "the magic number we are going for so everyone has comparable results" And then take that number and divide it by my 32 cups per day result. "90 / 10 = 9 then 9 / 32 = 3.5" I get 3.5 cups per day per every 10 gallons of my total water volume evaporated.

Please round up for your answers

Also here is a good litre to cup converter if you use litres instead of gallons.

I do realise that everyone is going to have different answers, I think my evaporation is on the high side. I have fans on the hood and my house is heated by a wood stove so I think this expidites the evaporation factor.

I voted for four cups. My tank evaporates 3.5 cups per every ten gallons dayly

I loose approximately three gallons per day on a 150 gallon open top, open sump, halide lighted tank.

 

[roscoe]

About 1 1/2 gallon every 24hr on a 40b.

300 gallon volume and i lose about 4 gallons a day... how many cups is that?

 

[trido]

I agree with the above posts. I have a 430 gallon system and lose three to five gallons a day depending on the season. You do the math.

I am sick so I did the math. 50 gallons a week, 7.1 gallons per day, 2.8 cups/10g

 

[skinz78]

About 1 1/2 gallon every 24hr on a 40b.

I loose approximately three gallons per day on a 150 gallon open top, open sump, halide lighted tank.

so 16 x 1.5 = 24 cups 150 / 10 = 15 24 / 15 = 1.6 su= so roughly 2 cups per ten gallons.

About 1 1/2 gallon every 24hr on a 40b.

24 cups / 4 = 6 cups per 10 g

 

[skinz78]

300 gallon volume and i lose about 4 gallons a day... how many cups is that?

4 gallons x 16 cups = 64 cups per day 300g / 10 = 30 64 / 30 = roughly 2 cups per 10 gallons.

I agree with the above posts. I have a 430 gallon system and lose three to five gallons a day depending on the season. You do the math.

we'll say avg of 4 gallons per day. So 4 x 16 = 64 cups. 430 /10 = 43

64 / 43 = 1.43 but we'll round up to 2 cups per ten gallons dayly.

Already explained this somewhere else, but I voted here anyways.

3 cups/10 gallons.

 

[skinz78]

Cool thanks for voting Charlie. I posted this on a couple of forums, I want to get a broad range of responses as possible.

 

[CarlaW]

Did I get the right idea over at the other spot???? I got a might confused earlier????

 

[skinz78]

Naw I think you got it correct, I'll look again.

 

[CarlaW]

Why were you thinking your evaporation rate was excessive?

 

[skinz78]

LOL cause putting 2 g per day in a 75 g tank seems like a lot to me.

Yeah you did it right on the other forum.

 

[CarlaW]

I really don't think that is to out of line, I put 1-1.5 into an 80 per day.

 

[burning2nd]

i dont understand why its worded like that...

I lose a 1.25G a day when the humidy is below 55%

 

[Herefishyfishy]

My question is when is the US going to finally switch to metric?

Cups, gallons, quarts, pints, ounces, teaspoons, tablespoons, what a mess!!!!

I lose less .85 cups per gallon on an "average" temp/humidity day , what kind of a number is that?
