Turtles are bigger in five years and filter having a hard time to cycle the tank as Steve said. You may want to add more Bio media than you have if any , that can help. Never clean any bio media with tap water it will kill any good bacteria that you have , use tank water and just rinse it off that brownish stuff is the good bacteria !
Chances are that you just had a algae bloom , it starts microscopic , causes cloudy water and good filter media will remove it in a few days.
Its federal law your water company has to give a "annual water quality report" in print , may of been on one of those inserts , look on there web site and see just what they are putting in the water.
