Last night I went to bed and my fish tank was normal. I had noticed nothing wrong with it, no leaks, no cracks, no nothing, it was perfectly fine. A little bit later that night, maybe 12 or 1 o clock, I heard a splashing constantly coming from the tank. I figured it was a little strange, but ignored it. This morning, at around 6, I woke up to super loud splashing coming from my tank. I jumped out of bed and turned on the light to see that my water level had mysteriously dropped halfway. The splashing was from the HOB filter dropping water from this new height. I frantically cut the power to the tank, and looked around for anywhere the water could have gone. I didn’t find a single drop ANYWHERE, it’s as if the water just turned into thin air. I’ve had this tank for maybe a month, and the room was the same temperature and conditions as all the previous nights. Any idea what happened to my tank water? Thankfully I hadn’t added fish yet.
