Dude,
Working with gravity and level is pretty difficult.

My set up is this:

My veggie filter is 2 feet higher than my pond. Pump picks up water from
my
pond (In your case at the bottom drain(good), and dumps it into the veggie
filter, then flows down back into the pond. Easy! Very Easy.

So what to do? Can you simply elevate your veggie filter and let the
water
return to your pond. If you decide to do a bio filter, then let the pump
run the water into the bio filter which will then dump into the veggie
filter and then into the pond. My 2 cents dude.

My problem is the BD...I put a lot of effort into it because it had this
magical reputation. If can solve my problem by moving the pump to the pond,
and pushing water to the VF, but then the BD is defeated. I am trying to
solve this and keep my BD in tact.

BV.
