Sump questions

This sump will be for a 160ish gallon tank. I don't know what type of overflow i should use nor do i know what type of pump.

Also, are there any suggestions on what type of filter media i should put in the second compartment?

You'll want some type of mechanical filtration. I'd highly recommend putting it upstream of the bioballs. In fact I'd recommend turning this into a wet/dry filter by avoiding submerging the bioballs. As for the second compartment, use it for the mechanicals. Things like thermometers, heaters, chemical reactors, etc.

what do you mean by mechanical filtration? like a canister filter?

No, some stage in the filtration that removes particulate matter from the water. Usually a sponge or floss.

You don't need all the different sections, and you definitely do not need a bubble trap. I don't have time to sketch anything up right now, so I will just try to explain it. Split the tank in half with a divider that goes down about 3/4 of the total height. In section 1 where the water comes in, you will want to make two different ledges. The bottom one will have eggcrate, and the top one will have a piece of acrylic with a whole bunch of small holes. In between these two levels is where you will put your bio-balls, and on the top level you will put your filter floss. The water will flow from the top down through section 1, and to the bottom of the sump, where it will go into section 2 to get pumped back to the tank. If you leave enough space from the divider to the bottom, you should be able to fit your heater(s) in there. It is very hard to explain, so check this out for an idea of what it needs to look like.

It has a black lid on it, so you can't see the filter floss, but that is the basic idea of a wet/dry.
