man you are so right ,,we were just up Dutch and a group of us were at the comet ,and this girl was kicking and kicking and was not going no where ,she made a cloud about a 30 foot you almost could not see the boat ,,,if that was the reef she would have destoyed a big part of it ,,,I tell who I dive with stay off the bottom about 8 foot this way they know it wont stir a cloud but most important not to destoye the reef,,,,this is a great practice
