180 gallon, 6'x2'x2' Freshwater tank, I'd just grab yourself a pair of Rena XP3 canister filters and be done with it..

Take pride in what you do, for it is a reflection of who you are.

Build your own? Like from scratch? The only time I really know of people doing that is if they have a sump filter. However, you'll still need to buy all sorts of pumps, etc. Generally, especially for a freshwater tank, a few canister filters will do you well and end up being easier and cheaper.

You'll need to buy a couple of filters, to get adequate filtration for a 180G. Rena, Ehiem, Marineland (Magnum) are all good brands. Look for the GPH (gallons per hour) rating. You'll want the total GPH rating of all your filters combined to be at least 800 GPH or so. Of course, this all depends on your stocking levels, but at the bare minimum your water should cycle through at least 4 times per hour.

The Fluval Fx5 would be adequate, but running just that would be risky, as you'd be in big trouble if something went wrong. Combining it with something like the Magnum 350 should leave you all set.

What sort of fish are you keeping in there? The four times per hour guideline would be fine with a more lightly stocked community tank, but if you're keeping cichlids or something more messy in there, you might want even more filtration. A couple of canisters as well as a few big HOB power filters (like Emperor 400's) would get the job done on a tank with a heavy bioload.

If the fish are still small, you should be fine with those canisters for a while. Once your fish get some size on them and really start putting out some waste, you might want to slap a couple of HOB power filters on there.
