DIY Canister Filter Pump?

So I made a submersible pump that consists of a motor, a plastic impeller, some wire, a switch, and a battery. I am planning on using it in a canister filter that I want to make. But will it shock the fish? I will be using 1-2 AA or AAA batteries which are 1.5 volts each. Will this work? I will be keeping a Betta and some RCS, maybe CRS and CPOs. Are they sensetive to DC current? Keep in mind that the part in which the electricity comes into play is going to be at least a foot away from the tank connected by airline tubing. thanks

Do not use exposed wires or home-made electrical set ups under water. Even a battery operated unit.

Buy a pump designed for this use (fountain pump or other). If you are off the grid there are 12 volt equipment that would run off a car battery or similar set up.

The rest of a DIY filter is a good project.

As for where the electricity will go, into the tank or somewhere else depends on where the nearest, least resistant ground is. Might flow through the tank, or it might flow through you when you touch the set up. Not good either way.

AA or AAA batteries will never be able to provide enough power to move the amount of water a filter pump is required to do. Even a very small filter will use at least 4 watts, and an AA battery would last about 30 minutes if it provided that power. A D size battery might last about 2 hours.
