Nice to see someone rolling their own. I've used water only in bubble
counters. At about 40-60 bubbles/min. refills weren't needed for
months. At 12-24 bubbles/min., well is a year too long to
measure ;-) ?
At 120 bubbles/min., I need to top off every four or so weeks.
That refill rates would be a function of buble rates is obvious -- but
have other had similar experiences with these rates? I imagine that,
the taller the counter, the less droplets that get carried into the
exhaust tubing and away from the counter.

If I had a lot of counters at high bubble rates, I might consider
glycerine. But then, if I had lots of tanks, I might not find counters
very helpful -- I'd be fiddling with the tanks all the time and know
them pretty much by heart.
BTW, how much a risk is glycerine, anyhow? Petroleum distillates, even
relatively non-aromatic ones like so-called mineral oil, would ride
like a film on the tank water surface until skimmed off (not an
attractive thought). But what about glycerine? Some humans imbibe it
frequently -- it's the stuff used to keep tobacco leaves supple after
they are harversted. However, that's not a ringing endorsement, is it?
Anyhow, we wouldn't expect it to be nutragenic ;-)
