Hi bro Jen, the cloudiness will probably clear up soon. From the deescription sounds like the water change may have adjusted the bb ratio within the tank. Will 2nd to bro Owain4, have always missed chemistry since schooldays. Thanks for sharing

Bacteria bloom. http://www.fishforums.net/index.php?/topic/246850-bacterial-blooms-explained/

Im guessing your tank doesnt have much beneficial bacteria because its bare bottom. Your tank probably holds very little beneficial bacteria and probably relies on the filter for most of the filteration work. Did you change your filter pads when you cleaned your tank??? you may have removed most of the bacteria. test for ammonia and nitrite

yes i have a very little gravel on the bottom of the tank.. good to know that why thanks
