That same issue happened with my Penguin 150 and 100 units. Doesn't exactly give you a secure feeling about shutting one down for a water change.............
Anyway, my Petsmart employee friend has a nasty filter setup like yours too. He grows Bamboo plants out of it on purpose, huge plants. That's just a filtration tank for his main tank though. It's setup almost like a saltwater tank setup.
I have house guests from back in Long Island and I can't spend my usual "tank time." That would be rude according to my wife..............Fish are people too I say!
