Brownish Clear Tubing

[Coen010]

I have the Swiftech 240-x and i swapped to tubing to PrimoChill PrimoFlex Advanced LRT, and EK-Ekoolant EVO UV BLUE premix 1L. But my tubing is brownish, how can i fix this?

that's bacteria / other living stuff creating a nasty film. do you have any silver coils / silver nitrate / anti-bacterial stuff added to the mix? plain water or even water with glycol isn't enough.

No, i have only added the premix, i thought there was some protection. But I think i have to buy a silver killcoil and new tubing then?

ok, that makes NO sense. if it's eco-FRIENDLY and biodegradable, then how can it have bacterial growth INHIBITION??? those two seem to be totally opposite, which would tell me it's either extremely mild inhibition, or they're just full of shit.

Probably should flush out system, and change tubing/coolant again. Tubing turning brownish could be some kind of staining, or something growing.
