Okay, so lets say I decide to go with Distilled water and biocide . . .

What are some highly rated biocides and corrosion inhibitors? I want inhibitors that would both protect against galvanic and normal oxidative corrosion.

I'm of course looking for fungicides, bactericides, and algicides, or even 3-in-one biocides would be nice. Something as effective as bleach, but without the corrosive properties would be great too. I was thinking rubbing alcohol, but someone said that probably wouldn't be a good idea.

Some links to performance tests to gauge the long-term effectiveness of the biocide would be nice if anyone happens to have any?

I've already decided not to chance using the silver coil due to the nickel-plated stuff that I'll be using in my system.

Yes yes, alcohol, bad idea, gotcha . . . what else can I use. Thanks for telling me about the rubber seal thing, I wasn't aware of that. The other person said that it also lowers the boiling point, and as most know, boiling causes bubbles.

Not sure why you think silver and nickel plate are not compatible. Only an issue if nickle plating is poor (seeold school EK issues) and ionizes in aqueous solution. Silver kill coil is still the metric used for biocide comparison. Check out a galvanic index sometime. Silver, copper (block), brass (fittings), and nickel are all next to each other. If silver would be an issue, then so would copper or brass. Now... aluminum is a totally different story... bad bad bad

Regardless of coil or biocide, you should be flushing and changing every 6 months. Ive run a year on water n silver no issue, so should is simply a recommendation. If you do go biocide, they all function similarly, so just try to avoid colored n such as they can pose issue.

If you need to worry about boiling and freezing points, you have bigger problems in your system than to biocide or not to biocide...

Because the potential for problems is mentioned in a lot of forums, and Koolance, right on their website says not to mix Nickel and silver or aluminum and copper in the same liquid system, and it's because of the potential for galvanic corrosion. I would love to have low maintenance, but for now, I will find something other than silver. I'm looking 8 years into the future here. I want my liquid cooling system to still chugging away

As for the boiling, you've seen the bubbles forming on the bottom of a pot not yet boiling. It's because only the water touching the surface of the pot is heated enough to create the bubbles. It really means nothing right? However, in a system where bubbles are a bad thing, small bubbles like that forming over time could create something substantial. I intend on periodically checking my reservoir anyway to watch for new air bubbles, but what if I forget for an extended period? I'd prefer not to be forming even more bubbles due to the lower boiling point. I may try it anyway just to see, but one other person also warned me that rubbing alcohol can corrode the rubber seals.

So far, you mentioned someone suggesting alcohol - bad- nickel plating issues in forums - 2011 posts about EK no doubt and no longer an issue - koolance CYA statement due to backlash because of EK screwup - has no bearing on anything really - an irrelevant reference to standing water boiling - bubbles dueto Iimpurities, distilled does not behave this way, nor does moving water - and an 8 year plan...

Not sure where you are getting your info, and I really don't want to know or I might start slapping people. Either way, you seem to have your mind set regardless of the advice you solicited so good luck and hope you get good results in 8 years

I went to Koolance website for giggles. Found your references:

"Water-based solutions are the most effective liquids at conducting heat (after mercury)-- better than alcohol, glycol, or oil. Alcohol and many types of oils should be completely avoided because they can chemically react with certain materials. For example, alcohol can cause cracks in acrylic." Right on their website it says don't use alcohol!

"Koolance's product warranty does not cover the use of 3rd-party coolants, coolant additives, or corrosion. Koolance LIQ-702 or LIQ-705 coolants are strongly recommended to help avoid issues with mixed metals or biological growth. Additionally, do not use aluminum with bare (unplated) copper or bare (unplated) brass in the same system. Do not use silver with nickel in the same system" if this is what you are referring to, does it seem odd that is added there when telling you that you HAVE to use their additives only? I guess that 70-75% of us on here are in trouble and systems that have been running for years with copper, brass, nickle plate, and silver coils are a complete anomoly!

You really need to read more from reputable and objective sources. Have you read the watercooling sticky right in the forum? Guessing not as every question you have had, and misinformation, is addressed in there. And it is 100% accurrate
