I ordered the Eheim Pick Up Internal Filter- 160 from the Aquarium Factory on a Thursday and it was delivered by Saturday morning - super fast for postage. My large [annoyingly noisy] tropical tank filter gave up the ghost on that Thursday. A blessing really, because it was a well known other brand [not purchased from the Aquarium Factory], which I will never buy again for my tanks. The fellow I spoke to on the phone at The Aquarium Factory was extremely helpful and understanding that my treasured tropical tanks needed a filter/s that was quiet and extremely efficient. The Eheim filter is fabulous. I highly recommend the Aquarium Factory for their customer service, knowledge and the postage time to my address was exceptional.
