food coloring?

distilled water + food coloring + biocide
is it safe for water cooling components?

Honestly I wouldn't even risk this.. if it goes wrong it's going to be costly, I'd just get a good quality coolant like Mayhems and be done with it.

^^ this. Would you rater save £15 now and spend £100's to replace parts or just pay the £15 upfront and have peace of mind that your rig is safe from discoloration.
 
Food coloring is edible so I'd imagine it would break down relatively quick. Distilled + biocide is a safe bet, but I'd also get an actual wc dye if you wanted to have it colored.

I just dismantled my loop this weekend and expected to find lots of growth. My shitty tygon tubing was completely yellowed so I couldn't see the fluid at all. I was pleasantly surprised to find the water inside still clear and free of any growth whatsoever. The tube was just junk. I didn't rebuild the loop, I'm going to wait until a completely new build, and just went with an H105 for now. My loop was distilled + biocide + silver kill coil.
 
To add, I would probably go with colored tubing before colored liquid and stay with clear distilled + biocide.
 
food colouring usually containes glycarin / sugar.. probably gonna break down seperate then stick to the hottest part of the loop.
i wouldnt use it..
 
i would go with colored tubes and a piece of silver in youre pump or biocide not sure if biocide rust silver.
 
i think its fine to use silver if your all copper. and dont use silver if you have nickel plated stuff. pretty sure its that way arround, but i never remember stuff right so i just say some pt nuke used properly.

been eying up some mayhems emerald green for my loop. but i may just go coloured tubes it wont really cost much in difference either way.
