Quick Cerges question:
I have a question with regards to flow direction (before I put finishing touches).
To be sure: The flow (from the pump/filter) enters the top of the housing. It then travels to the bottom. Water enters the riser (PVC pipe) from the bottom and flows upward and exits the top of the housing.
Reason I ask, it seems that I remember posts (can't remember if it was here or another website) where DIYers plumbed it the opposite way.
