I am setting up a very small tank (8 litre) to hold fry from my freshwater tank and am looking to rig up a small canister filter to cycle the water through. I want to have the pump located externally and was looking at this pump:
New Jet 800
From the specs it has adjustable water flow and can work externally as well which is ideal for me. My plan is to have the inlet tube located at the bottom of the canister and the outlet tube pointing back into the tank. I will run another tube from the top of the canister to the tank in order to suck up water. Am I correct in assuming that if the canister is well sealed the pump will create suction and pull in water from the tank via the top tube? Also do you think the pump I selected above would create too much flow for such a small tank?
