Any "must have" items for my H20-220 Edge kit?

[jalyst]

Interested on some of the heavily experienced folks thoughts on this, thanks!

This reinforces my suspicions, no need to drink the "coolant koolaid" hype!
Decently distilled or deionised h2o (or both)* + a biocide like Silver kill-coil or PT_Nuke** is sufficient!

In the H20-220 Edge, the metal parts of the loop are made of the following:
Radiator = brass tubes, copper fins, modified plenums: unknown?
CPU WB = copper base (is that it?)
Therefore like metals, but is that all the metal in the loop that'll make contact with water?

Even if they're the same or similar metals e.g. Brass/Copper/Nickel...
I wonder if there's more that can be done to inhibit the corrosion process?
I've seen some mention Hydrx, but it apparently has it's own drawbacks.
Is ensuring you have 'decently' distilled, DI, or both, the only thing you can do?

"must-have" items I've ordered, or am close to ruling-in/out:

Distilled/DI h2o: source YTBD; prolly a specialist local retailer, by all accounts distilled is more likely to be lower µS
T.I.M: .............. 1x Indigo Extreme 1156 kit; Ordered
Rad. Fans: ....... 2x Scythe GT AP-15; out-of-stock worldwide till Nov, relying on what came with my kit till ready
Biocide: .......... 1x 0.999 I&H silver kill-coil; Ordered, 1x PT_Nuke PHN; Ordered
Shrouds .......... Not going to bother at this stage...
Case fans: ....... Will see what comes with case, if insufficient I'll research, slipstream is among the best.
Anything else?

*I have found a few potential sources in my region.
**Not imperative if using kill-coil, good supplement in 1st fills if kill-coil hasn't settled, the less used, the better.

Good shops for Biocide additive/s (must ship to Oz)

Interesting side-reading:
-Nickel best for ant-corrosion? (not as good for heat-transfer?)
-Sacrificial anodes

stuff I may swap-in instead of the default parts (longer-term)
-tubing to mitigate microbial propagation
