Hungriee call me tonight i know whats the problem, I ran into the same issues when I had the tank. I ended up running two pumps to solve the low water flow when I split it off to the accessories.
As for the Bean animal system you need to set the siphon pipe about an inch lower the the open channel, that would make sure that the siphon starts first. Also make sure the open channel pipe is lower in the sump so it create more pressure on that pipe.
Do those two things and you should be all set. As for the pump I recommend getting one about 1200 gph or more if you only want to run one pump. The reason I say that is the way you plumbed the system. If you add up the length of all the pipes you are close to or over the 12' max and that is with out any elbows.
If you want redo the plumbing, bring the return pipe up to the top of the tank then split it to the two holes.You will cut about 4' of head pressure out and get more flow. This tool is very helpful http://www.reefcentral.com/index.php/head-loss-calculator i used it to get an estimate of what I would get out of the pump I had.
PM me if you need my number.
