Ditto. Sounds like the Maxi-Jet 900 is about the same. I plug it into a
power-strip that has an on-off switch. I also forget to pull the hose
out of the tank before/as I switch of the pump, so a little bit of water
is always siphoned back into the bucket from which I'm pumping. Does it
seem a little stupid to folks that in every aquarium book around, they
talk all about regular water changes but rarely if ever get into helpful
suggestions like a pump? I mean that's so stupid it's stoopit!
