BigBen (others):

I've noticed a strange occurance: When ever I add a small amount of anti-Freeze in the resevoir while everything is running, the bubbles slowly start to subside, but then eventually come back, I'm thinking it's because the temp of the added fluid... I don't really want to have to reflush the whole system, but I might, even though the bubbles aren't really doing much (if any) harm, I don't like them there (grin). One other thing that I've noticed is that when I fill my drainage tube with water, and seal it off with a rubber stopper, the fuild level starts to slowly disappear over a weekly period, I'm thinking that the foam bubbles are evaporating away and thus fuild is being wasted (gaseous form)?...
