The Best External Fish Tank Filters in the Market

When it comes to taking good care of your friends living in water, proper filtration of the water is certainly a priority. Fish produce a lot of waste, mainly ammonia, that needs to be flushed out of the water.

In a natural setting, nature has its way of dealing with this. The waste may be washed downstream or maybe insignificant considering the huge volume of water in their natural habitat. However, in an aquarium setting, the volume of water is not just enough to dissolve the waste to levels that are healthy for them.

This is why you need to get the best external filter that will  meet the healthy requirements for your fish.

External fish tank filter setup

So, do you again go and buy additional materials for setting up your canister filter? The answer is no. The packages of the external fish tank filters recommended here usually come with everything you will need for setting it up.

To assemble the parts into a unit, first, you need to link together with your inlet pipework and attach it to the green hose. Then assemble the outlet pipework and attach securely to the green hose. After this, connect the ends of your inlet and outlet pipework to your tap adapter.

If you are experiencing difficulty attaching your hose to your pipework or your adapter, use this trick; soak the ends in hot water for a few minutes to make it more pliable. Ensure that all filter media is rinsed thoroughly before use.

Before attaching the head to the body, fill the canister with clean water to just above the top of the filter plate. Firmly connect the head and the body and fasten the clips. Once the head is securely in place, connect the inlet-outlet tap adapter and push the lever down into the open position.

For purposes of priming, locate your inlet-outlet pipework into the aquarium ensuring they are fully submerged. You can move the spray bar above the water line once the unit is fully primed.

Ensure you remove air from the system as much as possible before powering on the unit. This is done by pressing the priming button and holding for three seconds and releasing it to fill the inlet pipe with water. You may need to do this a few times.

It’s now time to connect your unit to a power supply. Allow the external filter to run for a few moments to clear out any air. You can use the priming button to hasten the process.

Once your external filter is primed and operational, you can position your spray bar above or below the waterline. Spray bars are optional but they really help in oxygenating your water and will evenly distribute your outlet water flow.
