I have a 2.5 gal tank housing 1 Betta fish. I've gone through two filters (One was in-tank and the one now is under-gravel), and slowly, little by little, I've noticed that the water level in my fish's tank is dropping. It only does this when the filter is on.
Why is this happening, and how can it stop?

All fish tanks lose water through evaporation, especially during the winter when you have the heat on and if you don't have a top on the tank.
If you have a pet cat and you don't have a top on the tank it might be drinking from the tank, which could be helping lower the level of the water too.
You didn't indicate how much time is passing, but a 2.5 gallon tank is very small so you are going to notice it more than if the tank were a 20 gallon or larger.
One thing you can do to make sure your under ground filters aren't causing the problem is to check for water on the outside of your tank while your filters are running. Make sure your hands are completely dry and and feel around back there, and even check the hoses coming out of your tank.
My brother and I had several 10 gallon tanks with tropical fish when we were younger. Now, I have a 75 gallon. I also had a 55 gallon, but I sold it a while back.

It is evaporation, and the air bubbles make more evaporation by the air breaking the surface of the water and atomising.The heat from the lights also play a role .
I have a six foot tank, and i can see the level dropping each day.
Amazing how much the water level drops in a week.You can top it up with fresh water, but not large quantities because of the chlorine & chemical content, and the temperature change causes ick ( white spot ), if the change is too sudden.
I usually catch some rain water, or put tap water in a large container out of the way somewhere and let it stand for a few days to settle before topping with it.
interesting to know that pure rain water is not good for fish.

Evaporation occurs in every fish tank and is completely normal. All you have to do is pour a little bit of water in there every couple of days if you really want to stop it. As for the water going down when the filter goes on, its because some of the water is in the filter.
Good Luck!!! :0)

Maybe the bubbles from the filter are making the water evaporate faster. As long as the table, or whatever the tank is on, isn't getting wet then you don't have anything to worry about.

If the accurate of the tank is open, than you're dropping water by using evaporation. The water on the accurate floor evaporates and after a lengthy time period you are able to lose a respectable volume of water. i desire that permits

Is it covered? If not, evaporation will claim a fair bit of water. Is your house very dry? Do you have a de-humidifier?
Or if not, then you have a leak in the seal of your tank -- a small one by the sound of it. Try a tank that is plastic, an all-one-piece rather than a glass one whose pieces are siliconed together.

you can't stop the slow loss of water it is probally evaporation unless your filters are leaking out of the tank

Evaporation. Do you have a top or cover for it?
