Hi all,

I was wondering i still have a bottle of Pt-nuke PHN never used it maybe opened can't remember if i opened or not...that was years and years ago probably somewhere in 2009 to 2011 can't remember its years old that i do know. Can i still use it without the worry for having lost some of its potency to kill?

If not is this product the same?

Pulse Modding BioClear PHN

Want to use this with full copper blocks for cpu and gpu in my next upgrade.
What if i use nickel plated quick release fittings like those from Koolance should i use a corrosion blocker if the answer is yes what do you recommend?

Thanks in advance
