Our new pond (taking forever to get finished) will have a upflow veggie
filter with about 12% more surface area than the pond's.
What other filters should be put in?

What plants ? You will have no ammonia, nitrite or nitrate problems
with this filled with WH or lettuce. Can you grow these successfully
where you live?

To really polish the water, you will need some sort of mechanical
filter, could be polyester batting, sponges, brushes, or in larger
ponds a sand filter. When maintained properly, these can also provided
biological filtration too.

A UV is very helpful, it will cut down the burden on mechanical filters.

Pond is 700+ US gallons. Pump is overkill (Sequence 750 series
4200SEQ12, 2300 GPH) but we will be adding other water features in the
future. (Boy, that AZponds is REALLY inexpensive for pumps!)
Intake for pump is a no-niche skimmer and an intake at the bottom of the
pump, both 1.5" pipe. (Bottom intake will be a DIY Tetra bottom drain
http://www.azponds.com/Bottom%20Drains.htm with that will act as a plant
stand).
Should I put in some sort of trickle tower as well? My "pump house" is
in the storage room. At floor level it is about 12" below the pond's
surface. A trickle tower could be put on a stand of some sort.

I am after clear water. Pond is block lined with granite tile (or will
be if it will ever stop raining so I can finish sealing it). I could
add a UV light if required.
