I have one side mounted unit which I have tried running at 2 to 4 times water turnover. I believe as long as your outlet it high up from just below to at the water level, the flow in the tank is not going to be really bad. Most hob or canister filter are going to be much much stronger. Get a adjustable water pump so that you can adjust the flow between 2-4 times your requirement and you should be fine, The suction on the sponge is also going to be so weak that I doubt any young shrimp is going to be stuck on the sponge from the suction power due to the large surface area.
