Bear, with the offsets from selling other equipment, and getting some excellent used equipment, I'll have about $45K in it. It should reduce maintenance and last for years to come. In comparison, one fish farm just built an all new unit with 2 smaller haul tanks and one LOX tank that will hold one third what mine will in nearly the same size foot print...his cost?..$128K.

The haul tanks I found are very unique and were built at cost by someone that builds surfboards wanting to try this, material cost per tank was $11,500, 6 years ago. I bought them with oversize oxygen diffusers and O2 flow regulators worth over $6000 per tank., Heck, each gate valve to drain them or stainless handle to close the lid is nearly $100 each. I saved about $12K by "stretching" my old aluminum bed over building a new one.
