How fast does your water evaporate?

[kingfisher62]

Lately it seems that the water in my 55g FOWLR tank is evaporating extremely quick . I would swear I have a leak but can not find a trace of it.
Seems to go down an inch or more a week it has a glass canopy but it has some openings in the back .
How fast does your water evaporate?
Is it from the dryer weather?

I think tanks do get more evap in winter due to less humidity. Have you added anything like a more powerful MH bulb or a fan blowing on your water?

[drstupid]

my system loses 2-4 gallons a day at about 2.5x volume of yours. in the winter, my steam heat dries out the air a lot and it evaporates a lot more. it's particularly obvious this time of year, when there are some days the heat is running a lot and some days it isn't running at all.

I just got a couple new bulbs but they are just NO florescents so I doubt that is it. Maybe you are right about the humidity.

[chucksta1]

3 - 4 gallons a day

[MTB]

1-2 gallons a day. Or about an inch everyother day.

[erendon]

2-3 gal per day, 5 on a good day.

[JuzDuky]

2 gallons per day from my 90 gallon.

Used to be a reliable gallon a day from my 54g bow with 30g sump. Maybe more than that now, since the move: topoff is now automated and I'm not totally sure, but it eats up about a 15 g reservoir fairly often.

[AquaReeferMan]

2-4 gallons a day in my 125g.

[salth2owannabe]

4+ gal every other day, or every third day. Some times my skimmer kicks into a wet mode, and I loose a little more.

[Purple Haze]

~1gallon a day on my 60gallon system with a single 250w ROIII.

[richofoz]

about 1g a day in cooler months up to 3g a day in summer...

[corals b 4 bills]

My 155 (200 gallons total) eats about 2 gallons a day not bad considering I'm running 1000 watts of halide light and 15 pumps, the good thing is my tank is staying between 80-82 this year. fans blowing across the tank or sump really slurps the freshy.

[fastfish]

about 8 gallons a day in my 320g tank.

[jimmyj7090]

about 4 gal a day out of 180G

[flyyyguy]

roughly 5 gallons a day in my 90 and 7 in my 225.

[reptilemanmark]

2-3 gallons a day. 144 half round

[onano]

About 2 gallons a day on my 75 w/ a 25G sump.

[Frick-n-Frags]

about 1.5 gallons/day on a 60long with 20 gal sump and beefy flow.

about 1/2 gallon a day on my 50 gal rocktank with mellower flow (ex fuge now offline, packed solid with LR I don't have an immediate use for, so I'm running a rock tank :D)

so I guess for 120 gallons total about 2 gallons/day, and it goes up mid-winter and down mid-summer

[kingfisher62]

Wow, all those numbers are amazing but I can see why mostly everyone has some pretty extreme lighting compared to mine.

Anyone with NO lighting?

Do you think covering the top more efficiantly would help?

[dbuesking]

I loose 2 to 3 gal per day on my 125 DT and about 1 gal per day on the 55 QT

[fishquaria]

I've a thirty gallon tank... About one gallon or so a day... it varies... But one gallon is the average... It can drop more than an inch in one day if the top off isn't working.

[Redstratplayer]

1.5 Quarts per day on my 20long with 10g sump

[daven]

About 2 gallons a day on my 180 with t5 lighting.
