I'd like to get some advice on how to set up a bean animal on a 55. I'm not sure what size of pipe or pump to use. I've never used a sump before, so I don't know a lot about them. I think I'll use a 20 gallon aquarium as a sump. I know turn over of 10 times an hour is generally recommended, so I guess I'd run a pump that would do around 5 to 6 hundred gph. If that's not enough flow you'll have to let me know. I know I'll have flow loss for head, so I'll have to get a slightly larger pump. I'm not sure what I'm going to stock the tank with yet. If you need more info just ask. Thanks.
