Coolant level dropping on a sealed loop

Some of you lads might remember Christmas time the nightmare I had with the 2 580's and the duff block from XSPC. Well, I sorted it a couple of months back with a 690 and an RX360. The thing is...

The coolant level is slowly slowly dropping, and there's no leaks anywhere. It's probably about 1cm down from where I filled it too max now, so nothing major, but I can't figure out where it's going because everything is completely sealed tight.

Is this normal? Thanks.

If you're not leaking, then you must be clearing airlocks from somewhere. Try re-bleeding your system.

Yep, still probably small air pockets that are slowly working their way free. You will lose some water through the tube walls over time but this is much slower.

Thanks lads. Ive noticed some very small bubbles doing the rounds.
