 Re: How to make a sump
It's not a big deal unless you want to drill your tank.
Otherwise shop around for pre-filters and a sump pump in addition to your sump.
A Mag Drive, SEN, or Eheim internal pump would be great. Eheims are more expensive but they are great and durable as hell. You want a pump that will turn over your tank somewhere between 5-10 times an hour.
For a sump I would probably get a 20 long aquarium. I used a ten gallon on my 30, it worked, but there wasn't a lot of room.
Put your skimmer, heater, pump, etc.. in your sump. Fill it up to about 30-40%, start your siphon for your prefilter, plug in your pump and your done.
