Cecil,
I know you have been busy man. No problem at all. Sincerely...
Cecil , i didn't have lot's of options for the pool. "Settleable solids" ? What does that mean?
I can get such a thing. Works?

I am building it this Thursday.
What kind of pump to get?
For your size tank I would get one of these for moving the water:

You will also need an air pump to aerate the fish tank and the biomedia.
I would suggest one that produces 60 liters per minute like one of these:
http://www.bluewaterpumps.com/air-pumps.phpYou will need to build two filters: one that filters out suspended solids and settleable solids that get sucked into the siphon before they settle, and one that detoxifies the ammonia that is primarily given off By the fish's gills.
Suspended solids: solids that consist of fecal material and uneaten feed that stay suspended in the water column due to a lower specif gravity than the water.
Settleable solids: same as above but heavy enough to settle on the bottom.
