When I woke up this morning, I noticed I had a cloudy tank. At first I thought my eyes were still getting used to the light, but when I came home the water was still the same. Any ideas how this could of happened?



NOTE: I have gone through the cycle already.

Whitish cloudy is a bacterial bloom. Common in new tanks. It's the bacteria that eat debris in the tank. Here's a good article that explains it yb Dr Tim at Marineland.

There's a bunch of good articles in Dr Tim's library

Thanks!
