Will the flow through the gate/ball valve be really restricted to only allow a small amount of flow through the shrimp bottle? I'm guessing yes to keep all the shrimp from being pushed into the tank at once. And the output of the shrimp bottle after the ball/gate valve to keep from returning some of the shrimp through the bottle again right?

Yes, I forgot to add it to the drawing but I would put another valve on the line to the bottle to restrict the flow even more.
I'm not understanding this question 100%. The bottle will be a plain bottle (probably a 2litre) with the bottom cut-out where the surge forces them out and to overflow into the cup. The flow rate would be low (valve almost fully closed) as most of the surge would be the drain airing out between surges

Raspberry pi + peristaltic pump + L293D integrated circuit and some searching on Adafruit.com and you'll have it in no time. If you need help give a shout. I just set these up on my tank to dose NOPOX and food

I thought there was a second line coming from the bottom of the bottle in your drawing, going to the tank via the pump return line (from E thru D to the tank). If that was the case, some of the shrimp (from E) would be pushed back through D to E again.
If that's not how it's setup, then no worries.

Then you shouldn't have too many problems from what I see.

So, hmmmm...what I'm seeing in this drawing, and correct me if I'm mistaken by your intent, that you plan to use your ball/gate valve to redirect a small portion of your return-to-tank stream into the shrimp bottle. The shrimp bottle overflows, dumping some of the shrimp into the sump which then in turn will eventually get sucked into the pump and go up to the tank?

Honestly, i don't think that's worth it. The quantity fed will be completely random, sometimes being nothing, other times being a lot. You have little to no control over how much overflows etc... I don't think its going to work very well long term.
I highly recommend an automated dosing system.
If you want a write up, wait until this weekend. I am presently home sick from work battling a cold but i expect to be healthy in a day or two and can actually do the writeup for the parastaltic pump. Or i can make one for you and ship it to you. Not sure where you are located?
It's pretty easy with a raspberry pi to DIY but there is a significant amount of setup required to get the PI itself ready to rock and roll, with some UNIX knowledge required (though you could probably limp through it using the internet?). A PI is more expensive and has way more computational power than you really need if all you want to do is dose food every so often. An arduino is basically a dumb looping machine that you (or I) can easily setup and it can be very small.
Give a shout and let me know.
