LIQ-702 air bubbles

[Nadoedalo]

I have horizontal rezervoir, something like 60% filled(enough to full cover pump drain, and turn-off the pump and passive flow of coolant left in the tubes).
The problem is that it's not clean like water and more like white(maybe like some kind of foam or is it an air).
Should I worry about it or it is OK? Do I need to dissasemble reservoir and fill it with more in order to remove the air? Can those bubbles affect performance?

If you have something like a tube res laying on it's side it has to be more at like 95% full not 60% otherwise due to the typical positioning of in input/output air gets cycled in the system causing bubbles.

Yeah, it seems that it needs to be filled to cover both output and input holes, done it yesterdey - and now even a pump is more silent. I hope I haven't broke it.
Also PMP-500 pump is VERY high frequency loud, Koolance staff actually should warn about that or at least include 12 to 7 molex switch, it would be helpful.

It became quieter because the pump wasn't ingesting as many bubbles.
