I have been doing some experimentation with the difference between enclosed and non-enclosed tanks, pursuant to J5's comment/reference.
For reasons unbeknownst to me, there is a slightly discernible difference/advantage towards enclosing a tank.
I've always thought that was the case, concluded through the difference between my BB experiences and Cerotanks (same coil, but external), and now can confirm that the same holds true with Nauti coils, as experienced via the honkin'-huge Railbox, compared to when I just plop a Nauti tank onto an external device.
Proving, once again, that DD's artistic genius reigns supreme.
HAPPY FRIDAY, ALL!
Early start, early out-the-door. May the day end quickly.
