Look at the weak points of your durso/stockman pipe design.

Keep in mind that a great deal of flow is unwanted in a freshwater
planted aquarium. Everything you know about keeping fish is turned on
its head when keeping plants. You *AVOID* stirring the surface, you
*ADD* nitrates and phosphates, you only want enough flow in the tank to
mix the water up so that CO2 and fertilizers make it to the plants. Any
more is deterimental (unecessary at best).
