The title pretty well explains my prediciment, i woke up this morning to an incredibly cloudy tank. I can just see the back (and it's only a 10 gallon), everything is incredibly yellow but i've been trying to fight off some nasty diatom algae lately. I chucked a bag of carbon in their, hoping it would clear up but it's only been in for around an hour....anyone know whats up? should i be worried? what should i do to clear it back up?
