Cooling Probably a stupid question: food colouring

I'm using de-ionised water in my loop - can I add food colouring, or will it eat away at my pump/seals/tubing etc?

I would buy some proper fluid for it, but the last stuff I bought ate through my rubber seals in about 2 months, and leaked everywhere.

 

on one hand I don't think you should use food coloring, many have coal tar as a main ingredient and it could eat away at some rubber types, are they the kind found in a loop? I dont know but im not sure i want to test it out in my loop. Also it would make your deionized water more conductive.

Deep down i don't feel like any real harm will come of it. BUT I would advise using colored antifreeze, or colored hoses, or find a commercial made product like these... http://www.frozencpu.com/cat/l3/g/c...tives-Non_Conductive-Page1.html?o=rating_desc

Food coloring will come out of solution and sludge up stuff. Use a dye made for WC and use only the amount listed.

Pentosin (propylene glycol) comes in multiple colors and is perfectly safe for loops.

 

ta lads

 

I'd go with KayinBlack on that one

 

But not perfectly safe for colouring food!

 

but it tastes so sweeet
