I had an odd way of cleaning my tank, but it got it very clean. Since certain chemicals I purchased: waste/copper/and the like controls didn't always help, I used a toothbrush and a sponge to clean the sides of the tank and filtered through the bottom (I had white sand) with my fish net. It got out all that gunk and waste the best as it could. Rocks are usually easiest to clean with a suction or actually removing them from the tank and filtering through them in a strainer. The filter should clear the cloudy water on it's own.
I've never used bleach, but I read sites that say you can, but it's done in a certain way. You could look at this site about the bleach part: http://freshaquarium.about.com/cs/qa/l/blqa2006.htm
