Here's an updated schematic. In the picture I say you may need another ball valve on the other side of the "Y", but you will need it to adjust the flow correctly.
If you are feeling up to it, you can build a stream/waterfall (see pic below) that the filters and/or the other side of the "Y" not going to the filters flow into.
Whatever you do, you need to circulate and aerate the water somehow.
Use a minimum of 2" pvc for all connections and pipe (the bottom drains for each drum don't necessarily need to be larger than 2"). The bigger the better.
each of the drums has a bottom drain..is that the same as a valve that you can turn off and on to let the dirty water out? Yes. See the gate valves in the schematic above.
Also, the pump is attached before all the drums right? So it pushes the water through the filter instead of sucking it through if it were on the opposite end of the filter? I cant seem to find a pump strong enough. Do you think this would work?
http://www.lowes.com/lowes/lkn?action=productDetail&productId=25679-335-RSP10&lpage=none Yes, the pump is before all of the drums, pushing water through. Do not use pool or spa pumps! They usually use oil for lubrication, which will kill your fish, and they are not designed to run 24/7.
If you are going to use a submersible pump, I would recommend the Pondmaster 4,000 HyDrive Waterfall pump. Your pond is about 5,700 gallons if I remember correctly, so 2 of these pumps, each connected to their own filter system above will give you good filtration.
You can shop around on ebay and various pond supply websites for similar pumps. Always look at the wattage, because even though a pump is cheaper, if it uses more energy it will cost you much more in the long run.
External pumps are the most energy efficient, but cost quite a bit initially. If you want to use the retro-bottom drain that I talked about earlier, you will need an external pump pulling water through the retro bottom drain, and then pumping to the filter.
Also what is the purpose of the main bottom drain in the pond? What would be the difference of that and just putting a hose connected tot he filter at the bottom of the pond? A bottom drain in the pond allows for maximum filtration of particles (poop, dirt, leaves, algae, etc) because it pulls from the very bottom of the pond. Also, a real bottom drain eliminates unsightly piping inside the pond.
You can have a submersible pump sitting at the bottom and pumping to the filters, or an external pump with a retro bottom drain pulling from the bottom of the pond, but neither are as efficient as a real bottom drain.
At this point a real bottom drain isn't much of an option, unless you want to take out the pond and start over.
Hope this is helping.
