Fish Vegetable Symbiosis NFT System 100x50mm. A fish vegetable symbiosis loop needs three channel sizes for one reason: the fish side sets the flow. Also, a bigger bore carries it without the film running too deep. The 110 by 110 section is for high flow loops, the 100 by 50 for standard lettuce.

Plumb the fish tank to a solids filter, then send the flow through the channels at the rate the bore can carry without overfilling. Return to the tank through a sump.
Matching the bore to the pump is the whole design: too narrow and the film floods the roots, too wide and the flow slows until the crop starves. You can read more about the background of this method on Aquaponics.
