How much water do you lose each day due to evaporation? (POLL)

[Vanmo92]

Right about at a gallon a day, maybe slightly more. On a 72 gallon with 15-20gallon sump

I've got a 30 gallon tank and I lose about a gallon a week. While doing my weekly water changes, I normally remove 3 gallons and add in 4.

A gallon a week?!! Wow!! Why so little?

 

[Stubbs]

About 1 1/4 gal/day on my 90 and about 3-4 gal/day on my 220.

 

[aquariumrescueunit]

About 1.5 gallon/day on my 55

 

[maynardjames]

Bout 2 gallons a day on my 120

 

[diablomaster9045]

4-5 gallons a day on my 120g. I run 2x 250w halides for 9 hours a day.

I'm glad I found this post because I was concerned that my new ATO was malfunctioning about having to add water on a frequent basis.

I lose approximately 1.5-2 gallons a day.
125 gallon DT with a 30 gallon sump. LEDs for lighting.

I've only had water in tank for 3 weeks will update this in a year.

Thought I was losing my mind but after reading everyone’s posts the amount of evaporation is normal. 3-4G on a 90G display with a 13G frag tank plumbed to a 45G Sump, running 3 Ai Primes and a Hydra 26. Plus it’s winter and the house heater is basically always on

About 1/2 gallons per day for my 65g tank. More when we use reverse cycle aircon to heat or cool the house.

 

[samnaz]

Tank is 20g. About 1/4g per day.

230 gallon system with led t5 hybrid lose. 20 gallon brute trash lasts barely 6 days

 

[revenant]

I didn't want to necro this one but you all did it for me... so thoughtful.

I am loosing about 1.25g/day on my 100 with a 25g sump... my tank is only 5mos old now and I am adding the rodi manually... thinking about an ato though for less salinity shift...

 

[ccarr123]

Just under a gallon a day with 65 DT 15 gal sump. My skimmer is the main culprit on evaporation. With skimmer off about a half gal a day.

I got a 220 and I run T5 HO I think the heat from the lights does affect a little bit... but I'm around three gallons a day

 

[LRT]

Between 3-5 on 140 gallon system.

here is the log file from my apex for top off.

It takes me about 2-3 weeks to get through a 5 gal reservoir in my 20 cube. Running an AI Prime 16HD and a Nero3.

 

[ID-Reefer]

243 gallon system (reefer 900xl). Lose around 4 gallons a day. Run a 16 gal ATO tank plumbed directly to my RODI.

In my 10 gallon open experiment tank (neglected) which is currently cycling(?) I lose 2 gallons per 4 days. In my 75 gallon (open) with a 20gallon dyi fuge/sump I'm out at least 5 gallons every 3-4 days in winter. Dunno about summer days I set it up at the tail end and it was covered but i got tired of cleaning the covers. But when it was covered i would guess I lost maybe 1/2 gallon per 2 days.
