Hello everyone. I have been noticeing something with my tanks latly and don't know if it is because we have not had much rain or snow in the past year but my tanks loss more water now then they did six months ago. I have a 28 gallon nano cube that I have to add by rough estiment 8 oz of water a day to keep full. The tank is kept at 78 degrees witch is warmer then room temp for this time of year. But over the summer when we had that heat wave I was adding just as much water and the tank got up to 85 during the day from my a.c. in my house acting up and freezing. I figured since the temp outside is colder I would see less evap. I do now water temp and surface area exposed to air do all play a factor cause my five gallon doesn't always lose the same amount of water. That is about 16oz a week. Oh and I dint mind the extra evap now with the cold dry air outside. I walk into my house and the air is hummid and easy to breath. No humidifier needed lol. But back to topic.
I'm just worried about my new tank build. I'm doing a 225 and yes it has all the tops even the over flows. The sump even has covers . So by water volume could that tank once up and running lose over a gallon a day? It would almost seem closer to two gallons a day. That's a lot of water . I'm just worried about keeping it filled . I am doing an auto top off but may need to rethink it for an auto top off of the auto top off. At that rate ten gallons of top off wouldn't last a week. I'm try to set this tank up so I have to do less work to maintain it.
 
Water always evaporates faster in winter months because air is so much drier than summer when humidity is greater. I loose now about 2.5 gal. a day vs. about a gal. in summer.
 
I would think you would get more evaporation in the winter, due to the air being drier. I have a 30 gallon fresh water reservoir for my 70 gallon tank. If you can go bigger, why not? I'd be careful covering everything... May keep evaporation down, but it keeps heat in, and hinders gas exchange.
 
Do you have a gas furnace? Furnaces while heating the air also cook all the water vapor out of it. Which in turn causes the air to be drier. Try turning your humidifier on the furnace up which uses a water filter to add humidity to the heated air after it leave the furnace.
