<font color='#810541'>You need to do a buoyancy check!
Cylinders almost empty and you want to be neutrally buoyant at say 3 metres ideally. In fresh water with no added weight with 25 bar in twin 12's I am still slightly negative.
There is no formula, get out there and experiment, that's what quarries are for.
