The time has come for me to start thinking about adding a retrofit bottom drain to my pond.
I’m thinking about rerouting my periha 16000 pump 3850 gph through something similar

Currently it’s connected to a 1.5 inch corrugated tubing to my jebao 55watt I’ve clarifyer which I think Ian slowing down the flow rate of the pump a lot. Should I go with 2 inch pvc piping then straight to my filtration or just increase the pipe from 1.5 inch to 2 inch pvc through the uv then to the filter?
Thanks
