New pond and absolutely no idea what to do...

OK, I see your point. How about installing a external pump, and a port at the bottom of the filter? this would allow the water to filter and gravity feed to the pump, the pump then could go back to feeding the waterfall as your already set up for. Only problem is the external pump could be a bit pricey.

I was thinking of adding one of these (or similar):

55 Gal Drum Sand and gravel filter/DIY

The first line of defense would be floss and pump. Second line of defense would be sand/gravel filter.

By looking at the drawing, IMO, you going to have the same issue with clogging in the G/S filter. In order to prevent clogging in the filter your going to need to remove almost all the large waste out before it gets there. Your still basically going to have the same issues as your trying to suck the debris that is sucked throught the bottom drain through the submersible pump and now just grinding it up and causing the S/G filter to clog.

In theory, the first trash can has the prefilter to the pump, without all the stuff on top of it. Easily reachable and cleanable.

this would eliminate the larger debris from getting to the gravel filter.

let the bd gravity to a 55 drum with a clean out drain on it. wad up a bunch of bird netting in it and have an exit pipe towards the top of the barrel above the netting gravity feed to another drum to house the pump in, then your big solids will be left in the 1st drum

Therefore, I'll essentially need 3 drums.

Not if you replace your submersible pump in chamber # 2 with a pump like the Sequence 750 or Evolution ES Series pump.
