Tank is reef ready with center overflow box. Has 4 holes in bottom - 2x 1.5 inch drain bulkheads and 2x .75 inch return bulkheads. I plan to run a Herbie style drain setup. Intended flow through the drain/sump is a max of 800 gph.
Question: with that intended flow rate, do I:
- Use 1.5 inch plumbing for both drains - or
- Reduce the main drain to 1 inch and leave the secondary drain at 1.5 inch - or
- Reduce both drains to 1 inch
Basically just want this to be as silent as possible and have previously run the louder Durso mods.
