Just a reminder or two:
Use a one-way valve to prevent backflow.
Also use a filter on the pump inlet, especially if it will reside in a dusty location.
Maybe a pressure gauge on the pump to help diagnose any future airflow issues.
Use a simple pvc manifold where you connect pvc to weighted air line to balance air outflow to diffusers.
Good luck and happy aeration!
