Making the calculation for adding weight for salt water is really not difficult.
There is, salt water is .025 more dense than fresh water so you multiply .025 times your total weight including body weight with all of your gear on and that is the additional weight needed when switching from fresh to salt water.
If you and all your gear weigh 250 lbs then you would add 6.25 lbs (.025*250lb=6.25 lbs).
Thanks for the info, although I do know how to perform a buoyancy check, I was just curious as to if there was a commonly accepted percentage different. IE. In saltwater you need 30% more weight,
