I run distilled, PHN Nuke, and a kill coil in a proper loop.

For harsh environments, such as outdoors, high humidity, and salt environments fall into this category. Typically there should be not more than 0.15 V difference in the "Anodic Index". For example; gold - silver would have a difference of 0.15V being acceptable.
Index (V)
• Gold, solid and plated, Gold-platinum alloy : 0.00
• Rhodium plated on silver-plated copper : 0.05
• Silver, solid or plated; monel metal. High nickel-copper alloys : 0.15
• Nickel, solid or plated, titanium an s alloys, Monel : 0.30
• Copper, solid or plated; low brasses or bronzes; silver solder;
German silvery high copper-nickel alloys; nickel-chromium alloys : 0.35
• Brass and bronzes : 0.40
• High brasses and bronzes : 0.45
• 18% chromium type corrosion-resistant steels : 0.50
• Chromium plated; tin plated; 12%
chromium type corrosion-resistant steels : 0.60
• Tin-plate; tin-lead solder : 0.65
• Lead, solid or plated; high lead alloys : 0.70
• Aluminum, wrought alloys of the 2000 Series : 0.75
• Iron, wrought, gray or malleable, plain carbon and low alloy steels : 0.85
• Aluminum, wrought alloys other than 2000
Series aluminum, cast alloys of the silicon type : 0.90
• Aluminum, cast alloys other than silicon type,
cadmium, plated and chromate : 0.95
• Hot-dip-zinc plate; galvanized steel 1.20
• Zinc, wrought; zinc-base die-casting alloys; zinc plated : 1.25
• Magnesium & magnesium-base alloys, cast or wrought : 1.75
• Beryllium : 1.85
well im running coolent and i see alot of people are running distilled water what is the reason for that ive been reading alot and not really seeing why
Yep, they pretty much are the same thing. Removing hard chemicals and particulates is achieved in both.
The concern I had was silver to brass, which can be as high as 0.25. That's pushing the "medium" environment for corrosion. I doubt our components are made from high brass, which would bring the difference to 0.30 - I believe that's reserved for boat fittings and things of that nature though brass plumbing fittings may fall into this category as well.Considering we have a Humid environement but with no salts of chimical, i thin kwe can accept a lil more than 0.15 in this table. But 0.45 to AL is way to much !
Why doesn't anybody make a zinc anode that will fit in a reservoir?? Corrosion protection for those with aluminum rads.
