7500 gallon waterfall and filter

[Blueberry]

I am building a ~7800 gallon pond. I am seeking recommendations on if I should have 2 different biofalls and if so is it better to have 1 biofalls 6000 and 1 at 2000 or have them be even. Also is it recommended that they are at different locations for the pond? I also plan to have my waterfall 3-4feet above my pond.

my pond is 25 x14 x3.

any suggestions?

`I'd recommend one biofalls and a bog. actually I'd recommend ONE bog no biofalls. BIOFALLS equals regular maintenance. washing pads or lava rock and the surface area is way short of that of a bog.

careful with a 3 or 4 foot waterfall that's a large splash zone to control . including wind that may blow the falls out of containment.
