Hey guys I have a quick question about an aquarium I just bought. I bought it used and the person was using it up until I bought it. I filled it with water just to make sure it doesnt leak but when I got up for work this morning I saw that the water level was way lower and there was sweat all over the glass and the cement around the aquarium was wet. Is this due to it being hot and humid outside? The first couple hours after I filled it up I didnt see any leak and I still cant see any noticeable one right now. Would appreciate your alls help, I need to this tank to transfer my fish and turtle from my old one that does have a confirmed leak. Thanks.
