Tube not clear

[Liquete]

Good afternoon,

I am maintenace the liquid cooling, and the tubes are not clear.
It is as if some kind of algae or residue has been generated.

How can I clean the system?
What product do you recommend to clean it with?

Thanks for your help.

Best regards

That is quite simple. You need to flush the system properly & preferably with distilled water.

That looks more like plasticizer to me. This dissolves over time from PVC hoses and discolors the water and the hoses. How old are the hoses?

I never used plastic hoses and it turned like this immediately when I filled a biocide mix.

What liquid do you use exactly?

Got the same issue some time ago, when I added a pump and reservoir to my Eisbear I had the same greenish tainted coolant, I had to flush the system...
I didn't change anything before and the Eisbear was less than 1 year old

sorry for not replying sooner but I had notifications disabled by mistake.

the tubes are about 3 - 4 years old.
I have used premixed clear from alphacool and ewbk.
every year I have changed the fluid

cleaning the system with distilled water, and it has improved somewhat.

in the end I changed the tubes (I still have them).
I used the leftover tubes from the eissturm kit.

And the result? Is the liquid clear again now?

I'm sorry I didn't reply, I don't know why I didn't receive the notification.

Yes, the tubes are clean because I changed them.
The previous ones, after applying the distilled water, were free of residues but still discoloured.
