Froth and bleeding

hey guys i got my WCing stuff today.. connected everything in a loop, Pump >> CPU >> Rad >> Res >> Pump.. Then measured the Distilled water and Zerex(1:20) quantity and slowly filled the res. The Pump(Eheim 1250) is running fine, but there is a lot of froth in the water.. I have opened an inlet in the res so that air can rise up.. the whole circuit is running fine, no leaks.. but i'm concerned about the froth and bubbles.. does it always froth in new setup? and how long does it take to bleed? I'm goin to leave this on for next 24 hours.

thanks.

If your res/airtrap is efficient, it will go away.
Before turning on the pump try to tilt your case so major air bubbles can escape. It will limit foam formation later.
