Evaporation ??

[FishGeek]

I was just wondering why my tanks evaporate so quickly. within 2-3 days after doing a water change (and filling the tank to the trim on the top) there is about an inch of water out of the tank. I only have the light on for a few hours at night, so I am not sure what is causing it. Is this normal? If not what do I need to do to fix this? Thanx.

Is the room its in warm? Did the evaporation just start occuring motre recently or has it been a regular thing. Also what temperature is the tank ?

or are you in a dry climate or running a dehumidifier? Out here in 10-20% humidity, i could top off my tanks daily, i swear

If you live in a dry climate, you'll have a LOT more evaporation than if you live in a humid climate. I lived in Maryland and Pennsylvania, and it was SO HUMID there that I had just a little bit of evaporation. But here in Portland in the summers the humidity is extremely low, and it has also been hot to boot these past few weeks. Just top off and don't worry about the evaporation. Have you looked for leaks?

Yeah...around here evaporation is normal. If its something that has changed I'd look for leaks like Delta said just to make sure you didn't crack something or your filter didn't crack and has a slow drip etc. Otherwise just top it off

i have been away for a week... and my tank has evaporated some water.... its is common in hot places.... just top it up with new water

Ok. I am sure there are no leaks. Both tanks stay around 75 degrees F. And I have an airconditioner and 3 fans running in the room where they are so its not hot. (If I dont have those running, this time of year, it would be hot.) It has been happening since the begining but I just figured that I would ask. Thanks for all the answers.

It's the air conditioner, in that case. Air conditioners remove most of the moisture from the air, which increases the rate of evaporation. Just top the tank up every few days.

or if you have an airstone running...that can speed up evaporation.
