sorry, another K4 question that relates to the recent discussion... I just got a single Koralia 4 (will get another if I like it, in the meantime I've also got two MaxiJet 1200's). I'm wondering about the noise at startup (or noise during operation at all).
I've seen the earlier comments about the noise it makes at startup, and indeed mine is making it as well. However, its now been turned on for a good 5-10 minutes, and is still making some noise (though not as much as right when it turned on). In your experience, how long does it take for the noise to subside, or does it ever completely subside? So far I really like the flow, but if it won't shut up then I'm going to have to jettison it. Its definitely not rattling against the side of the tank or anything else. It just makes a vibrating noise that every so often goes away and its completely quiet, but very quickly comes back.
Thanks for any insight!
