Pump for this tank you are looking at needing about 2000gph or more, depending on if you are using mechanical or not. If mechanical you will need a high head pump.

Merbeast;1614221; said:The problem with reverse flow ugfs is that you need to break them down every so often to clean them out. Yeah, I know you use a gravel vacuum, but there is still waste trapped underneath (even with reverse flow), and it will reduce the filtering capacity over time for the ugf. It can also build up pockets of deadly gas and lead to "old tank syndrome". Now, picture this: breaking down, cleaning, and reinstalling a ugf in a 4' deep tank! Thanks, but NO THANKS! I say get a couple of fx5s ($400 shipped from JohnPTC) and call it a day.
