Corrosion inhibitor

Looking for an alternative to silver since nickel plating will be present.

Has anyone used 2 hydroxyphosphonocarboxylic acid/HPAA (also sold as Watercooling Anticorrosive AntiCorro-Fluid) for anti galvanic corrosion properties?

Personally I just use Toyota long life engine coolant, designed for water cooling loops containing any mixture of steel, iron, copper, brass, aluminium, nickel, tin, etc and has a 5 year service interval.

Never had a problem with it in a decade of water cooling, and works great in my car too lol.

Nope, what do you think us old school water coolers used before all these specialist fluids turned up on the market at 10x the price?

Engine coolant for fluid, Tygon medical/laboratory grade tubing, various plumbing fittings, Eheim fish tank pump with G1/4" adapters, jobs done.

Water cooling performance hasn't really changed in the past 10+ years it's just been made easier to do and prettier looking.

Used to use engine coolant additive as well back in the day. Never had any issues!

Just get as pre mixed coolant? less hassle surely than having to buy engine coolant?

Those of us with cars usually have a 1L bottle of coolant for top ups and you only need a 15-20% mix which is a tiny amount. Mines been running saab red coolant mixed with distilled water for 7 months.
