It has a solid construction with all the parts made to meet the basic needs of customers. Unlike many other filters, this model has stainless steel clamps.

EHEIM Classic External Canister Filter with Media Review

Review:

The canister filter manufactured by Eheim is definitely one of the most widely chosen models in the market. The model is designed for aquariums with up to 66 gallons and provides three types of filtration (mechanical, chemical, biological). Above all this, the unit is highly energy efficient.

What we think:

Coming equipped with quality components, EHEIM Classic External Canister Filter with Media ensures low-cost high filtration. Quiet and smooth operation, great functionality make it a decent model to choose for your aquarium. Although the installation instructions are poorly stated in the manual, the unit is quite easy to set up.

PROS

  • Noiseless operation.
  • Ensures no leaking.
  • Easy installation.
  • Low energy consumption.
  • Lightweight but sturdy construction.

CONS

  • Lacks coherent instructions.
  • Rather hard to clean.
  • Replacement parts are difficult to find.

How To Set Up The EHEIM Classic External Canister Filter with Media

Generally, canister filters are very easy to set up and you will get assured in this after buying Eheim Classic canister. Unfortunately, the manufacturer doesn’t provide users with clear instructions. These are difficult-to-understand diagrams. Instead, there are multiple good tutorials on YouTube you can make use of. For a savvy user, it will take no more than 20 minutes to have this canister filter ready to work. So, follow these instructions:

  1. Cut approximately 3 inches off of every size of included tubing.
  2. Connect the double tap adapters to the hose pieces. One valve handle must point up and one down.
  3. Fasten the hoses to the ends of the valves without yet cutting the hoses.
  4. Now you can assemble the intake tube and strainer, place it on the necessary part of the aquarium. Repeat the action with the spray bar assembly.
  5. Cut the hoses (make sure the length is chosen correctly). The tubing must have the right length to let the filter move from side to side while not hanging too loose.
  6. Be cautious to get a couple of extra inches for the connection once you attach the hoses to the intake tube and spray bar. This way you will be able to move it around without worrying about disconnecting them.

How To Prime The EHEIM Classic External Canister Filter with Media

Eheim Classic 250 is not a self-priming canister filter. So, you will need to prime it yourself after buying. Just follow this guideline:

  1. Till the valves are closed, the intake and outtake hoses must be filled with water. They must be installed on the tank with hoses full of water.
  2. The next step is filling tank water into the canister. Close the intake valve of your canister beforehand. After this close the pump head valve.
  3. Fasten the canister filter with the intake pipe and spray bar hoses. Make sure you have closed all the intake and outtake valves before it.
  4. Open all the valves and switch on your new Eheim canister filter.

Verdict

The importance of a good filter for an aquarium should never be neglected. And if you are into decking out your tank with the best available accessories, the EHEIM Classic External Canister Filter with Media is the excellent choice! This model will provide your fish with clean water while not producing any noticeable noise. However, you should be ready with some hustle when the time comes for cleaning the gear. We believe you are ready to pay that cost to have your dear fish live in a healthy environment.
