EK CryoFuel Coolants Now Have Extended Shelf Life of Four Years

maybe (because the coil is a solid (biocide),
but def not the liquid ones (from my experience; my converted and 3 friends (stock) eisbaer AIO, refilled with deionized + dead water).

if there is a tiny bit of exposed alu, it usually generates a galvanic reaction pretty quickly (within days, maybe weeks) ,
but on my last (custom) loop all parts were either painted or coated, and i had no problems using it either.

i dont want to know how many of the "loop started leaking/burst.." problems, were caused by galvanic reaction,
producing pressure that cant go anywhere, because the everyday user/non-builder didnt incl a (pressure) relief valve..

i would say using deionized is the exception to the rule, e.g. the "expert" is fine using it,
but to be safe, i recommend using distilled water, and not have to worry,
especially after i saw no benefit (cooling perf etc), besides lower conductivity.
