The last questions is do you stir up the bottom of your tank while you are cleaning?
Brine Shrimp are not that healty for fish, look into getting
mysis shrimp. Also you really only need to feed every other to every third day. I feed my fish like that and many other people do. Instead of bleach use vinager water mixture to clean your dead corals. It is safer for the fish. What kind of flow do you have? I know when i had my small tank with little flow it would always cloud up when i added more flow it kept it clearer.
