Starting on my water cooling loop and I was looking for a biocide. I was looking at PT Nuke but they don't have it at PerforamncePCs and DazMode. I was also looking at SidewinderPC and they have it but for me to get it I have to pay like $20-30 shipping to have it shipped to Canada. Are there any good biocide besides a kill coil that i can get on PPC or Dazmode? Also is "PrimoChill Liquid Utopia - clear" any good? I'm going be running distilled water with PrimoChill bloodshed red tubing.
