Its like hooking up your canister to a u.v or c02 reactor, they will all limit the flow of the outflow, and no harm is done
i have had good luck with these
Two Little Fishies Ball Valve w/ Hose Barbs for 5/8 Inch - (15.88 mm) I.D. Tubing - (1 Per Pack): Amazon.com: Industrial & Scientific
the motor does not slow, it runs at a constant rate of speed, and it is the pressure caused by that motor that i believe created the air leak, that prevented the syphon.
