I don't know what the price differences are, but if you buy the bigger one you can dial back the flow by redirecting the excess flow back to the sump... just need a tee and a ball valve.

Oh, I got mixed up. They have the 10000 in the DCP series instead of the 12000. It then jumps to 15000 after that.
I would recommend the 15000's so that you can run them at a lower power setting. However, I think the 10000 will work, but you might hear a higher pitched hum come from the pump at the higher setting.
Here's the thread about when I got my Jebao DCP 8000.

No need to use a tee in the sump as the pumps are adjustable and you'll also have the ability to dial back or increase the flow with your bean animal siphon drains.
When you 1st set it up you'll need to tinker with both pump settings and your valve settings to find the sweet spot. From what i understand about the bean animal theres less tinkering because of the open chanel drains.
I may have read this wrong but did you say 2 siphons and 2 e drains ? With a bean animal theres also the open chanel drain which take on a small amount of water, this is supposed to reduce the need for finer adjustments.

Here are the best curves I could find:
These are in metric, so you will have to convert, but you want to look at the blue line on the first chart and the green line on the second one. Using those should give you a pretty good idea of what your max flow will be at the 6.5ft head height. I will take a closer look at it later and let you know what I find, but I don't have time at the moment. Once you find the max flow, you then divide your desired flow (for a single pump, so half of your total flow) to get a percentage number, and this is a good estimate of the percentage you will need to run the pump at. I recommend aiming for a percentage of 60% in order to make sure there's no noise and for less wear on the pump. However, it is completely up to you if you want to go with a small pump that has to run higher.
Eh, I ran through the math real quick and it looks like the 10000 will flow about 1300gph at your head height. This one will need to be run at 100% to achieve 2600gph. Probably not the best choice. As I recall, you originally wanted 2800gph.
The 15000 can do about 1700gph at your head height. It will have to be run at 80% to produce 2800gph of flow.
The 18000 will flow about 2500gph at your head height. This comes out to just under 60% to produce 2800gph of flow. This is probably your best option. Your head height is really the factor. My head height is a little under 4ft so it allows my pumps to flow a lot more for that height (my tank is also not nearly as big).
At this point, although they are a bit pricier, I'd recommend two of the Jebao DCP 18000's.
I would go with the largest model pumps since you could probably easily run them mid range. If one fails then the other will have the capacity at a higher setting to run the tank with basically the same flow until you can replace/repair the other. I am running a single DCT 15000 on a 210 and it can more than get the job done wide open. I can't hear the pump even at 100%, but I do have a lot of other equipment running in the same room
Thanks for doing the math for me I really appreciate it. I will grab two of the 18000's as I don't want noise.
For the main siphon and open channel would you do 1.5" pvc and then 2" for the E drain. For the pumps 1" returns I assume?
LOL... that would work too! I don't know anything about Jebao pumps, but they look snazzy.
