What are you making the tank out of? You can always check out the DIY section for filter tips. It would also be better to start a new topic about your tank in the DIY thread itself. This way you will get valuable opinions and suggestions from dozens of other forum members.
To make you own you would normally just get a bulkhead fitting at your desired size and pipe to the sump with flexible PVC, Vinyl tubing, or PVC.
