Cloudy water, caused by a bacterial bloom, often happens in new tanks. If yours is 9 months old, and just recently started doing that, something must have changed. I don't think sticking your hand in the tank would do such thing, although I don't know your hands. :tongue:
Maybe something dead in there? Something weird in your water? Something wrong with your filtration? Hard to say...
