Those tanks are the CNG buoyancy tanks. Those two tanks give me 1,000 lbs buoyancy net including 3000 psi of air

In your case you would dig a ramp into the pool then lift the sub to put in the liner.  I am sure you have obstacles that I am not aware of, but it is really worth it.  I am lucky because I have the space for it and the machinery plus our water is not metered.

The buoyancy tanks are behind the occupant sphere, so I was worried I would not be able to balance it.  Turns out my math is spot on and the sub balanced out perfectly.  My pool is is pretty simple, it is a hole in the ground with a liner.  I have a removable two part lid so animals or people can't fall in.  I will leave it full of water over the winter so I can do the final tests in the spring before the lakes thaw out.  I will send the picture in the next email because I am experimenting to see what size picture I can send from my phone.
