I have not made a dive with my new steel tank. With my equipment and an AL80 I used 10lbs in fresh and 22lbs in salt which is a difference of 12lbs. Now my question is, if I test my weight in fresh with the new steel tank and just say I now use 4lbs in fresh (I am not sure of the actual number since I haven't been in fresh with the tank yet), is it safe to say I should start with 4lbs plus the 12lb difference and try that in salt as a starting point and adjust from there? or is there a better way to calculate going from aluminum to steel. BTW it is a XS Scuba HP100 steel if you are wondering. I am just trying to find a starting point so I can adjust and then do my dive and hopefully fine tune some more. I have posted the specifications of the old cylinder and the new one.
