Gouri, There are 2 types of BD, one with air diffuser and one without. Mine has air diffuser and NO I don't clean the bottom of my pond coz it's always clean Due to the mushroom effect from BD diffuser it helps to sweep/push the waste to the BD. You can still have a normal BD but you need to add a few TPR's to assist the water flow towards the BD to clean the floor rgds, Jon "DuKu Friendly" _____________________________________ "No one is ever too old to know better" http://s3.photobucket.com/albums/y63/Koi38/
