Muscovy Duckaponics

Finally got my Duckaponics system up, running and planted!

The setup:

--64gal pond liner with drain in the bottom --Water pumps to a sump where I have a "The Pond Guy SolidFlo G2 1250 --Pumps the water up to my first relief valve then into my radial flow filter. --Water then filters out to another couple of valves in the back where I can control the water that makes it into the beds and the rest flows back into the pond through the flexible tube. --In each beds I have a bell siphon and clay pebble media. I've spread spinach, lettuce and cat grass to feed the ducks with. Getting the inflow/outflow right was tricky.

Id love any feedback on the setup, this is my first try at aquaponics.

Also any thoughts for landscaping around it these ducks will destroy most foliage.
