I'm in new territory with a 110XH (48x18x30"h) that I want to filter with an OC 340 and external pump, I could use some help. I'm a pool guy and I'm trying to keep things simple and efficient, but this isn't a pool and I want to be sure I'm not overlooking or oversimplifying anything. My specialties don't really include plumbing, anyway.
The plumbing will consist of a simple hang-over closed loop, the pump then filter and back to tank, nothing else inline. No heater, no reactor/injectors (low tech), no UVS etc. I plan to use numerous ball valves (black/white circles in diagram) and threaded unions (grey rectangles) to isolate components for easy cleaning and disconnect. I want high flow in this tank, so much as to require adjustment down on a ball valve, I don't want to undercut it and wish I had more flow after the fact. This will be a planted tank, not a reef, so I don't want to shoot too high either. All the external pump info I'm reading is pretty confusing. Height from floor to the top of the tank will be approx 6'.
Questions:
1. How many GPH would you choose to pump this setup considering I want substantial current in the tank?
2. Ocean Clear suggests a pump on the higher end of their suggested range for an OC340 (500-1600gph), what are the downfalls of not doing this?
3. The OC340 has 3/4" connections as do most of the pumps I've looked at, should I maintain 3/4" plumbing throughout?
4. Will PVC flex (where pictured) cause any problems?
5. Do you see anything missing, redundant or wrong in this diagram? Thanks in advance - J
Edit: diagram is updated. The black triangle is a check valve
