With a deep pond, and being pump fed it would be a good idea to have the pump at the lowest point of the pond to suck up all the debris fallen.
Skimmers are good for surface debris.
Many of us don't want to buy a filtration system :p, and from what I linked you to before they were home made DIY filters, so some spending of $$$ is necessary, usually for the plumbing and the containers needed to hold the filtration.
For such a huge pond, you could always try recycled plastic vats/barrels. In my part of the world, they're called Drum Recyclers, my drum is around 200 litres in size and cost AUS$30. How many would you need? Seems like a lot, considering if my calculations were right, that you're pond is close to 180,000 litres, you might need 10? If more, plus lava rocks if you intend to keep something that large clear to the bottom.
I'm already mind boggled at the size of your pond idea and would honestly tell you right now, that without a bottom drain there will be debris all the way down, and without a large enough filter, it will certainly be dirty, however, do try and read this other site on another DIY filter:
