Does anyone have any experience with this filter? I read through 60 reviews on this filter on ebay and 99% of them gave it 5 stars and said it was awesome. I want to buy 2 of these for my 125 gallon tank. This filter is rated at 530 gallons per hour, so with 2 i think they would be fine. Even with the reduction in flow when you add media to them. Anyone with any advice of this filter please fill me in.
