[Amps] WATER for vapor cooled amplifier

[Harold Mandel]

Okay, so let's back up one step and sorta tabulate our findings
and observations:

1. Someone found that Deionized water was too conductive.
2. Altronics says never to use DI water in loads.
3. Someone found distilled water too conductive.
4. Altronics says distilled water is too reactive, also.
5. Some people find Zephyr Hills distilled water
    not too conductive and okay.
6. Altronics says clean, potable tap-water with less
    than 500 parts per million of debris is okay for
    RF loads.
7. BIRD says distilled water for loads is best.
8. Paul found one water source supposedly good, a
    dead short.

My head is beginning to spin!

The idea of putting the HiPot tester in the water seems
the top winner today.

Water, at it's best is supposed to be at pH 7.00, yes?  
Then, it's at 1.00 Specific Gravity, yes?
That should mean it has a certain conductivity, yes?

Why would potable water, not distilled or DI, have a different
conductivity between brands?

Discounting the DI story, why would distilled water be 
harmful? Why would it have differing conductivities
from brand to brand?

Lastly, Altronics says to include a "people-safe" antifungal
agent in recirculating systems that does not include salts
or any other caustic agents. Do any of you use antifungal
materials in your recirculating or vapor-phase cooling rigs?
