obviously I'd test out food coloring that is water soluble

and yeah, it will definitely tarnish the tubing but thats the least of my concern
but will it form precipitate? clogging?
will share more after i read up on it ay

compact cooling = COOLIT

1st rule of WC...is leak test
i run mine bare w'o hardwares attached for solid 24hours run
some even recommend to do it for 1 week

IMO the main cause of failure in those kits are its quality
i had a friend TT kit leak due to an acrylic crack on his waterblock
i blame this on its build quality
and also tubing wise, overtime it will degrade
just like those garden hose

most of DIY such as tygon tubing and swift pumps are industrial standard
there for it should have a better quality than those kits
don't get me wrong, but even DIY kits w'o proper setup and preparation are also prone to failure

like i've said before, not all kits are rubbish
i'm not too sure on what happened to that domino ALC
but last time coolit eliminator worked fine with me

maybe that guy yank the loop too far and made the connection loose
who knowss
