Evaporation is a possibility.

I'm sorry for the wait- you could do that. I'm not sure if it would help, but it can't hurt!

My smaller tanks drop about an inch every 4 days or so this time of year. If you do not have an easy source of demineralized water, do your water change every week and make it a bit bigger than in summer. If you do have an easy source of DI water, it can be used between water changes to top off the tank. I happen to have an RO in my kitchen sink so I do a lot of topping off.
