If your Seachem Tidal 75 or Seachem Tidal 110 hang-on-back power filter appears to have a low flow rate and/or is sounding noisier than usual, then we recommend cleaning its impeller. In extreme cases, you may also want to replace the impeller completely.
To see how you can perform both of these actions, you can take a look at this tutorial from Aquarium Blueprints.
1. Before doing anything else, make sure you unplug the power cord of your Tidal 75 or Tidal 110 from the power outlet.
2. With the power of the filter turned off, you then need to remove the pump housing by taking the following steps:
- Have one hand squeezing the area just above the pump hosing, which is located directly below the surface skimmer of your filter.
- With your other hand, pull the pump hosing downwards to remove it from the bottom of your Tidal 75 or Tidal 110.
3. With the pump hosing removed, you should see the power cord being attached to its channel. Slide the cord out of the channel so that it won’t block the removal of the pump.
4. With the power cord out of the way, slide the exposed pump from the bottom of the filter to the right.
5. After removing the pump from the filter, look for a clip located at the top that is holding the impeller cover in place.
You need to carefully lift the top clip upwards and then slide the impeller cover off.
6. One last part you need to remove is the circular cover. In order to remove this, twist it to the left and then pull the impeller outwards.
7. After you finally got the impeller out of the pump, you can start cleaning it.
We recommend using tank water you plan on removing from your aquarium to rinse off any debris you see on the impeller so that you won’t harm the beneficial bacteria.
If it is extremely dirty, then you can mix in some vinegar for the tougher spots. If you decide to use a vinegar mixture, make sure that you thoroughly rinse the impeller before putting it back into the filter as you don’t want to accidentally add vinegar in your tank water.
8. If the impeller appears to be broken and/or appears to be quite dirty even after a thorough cleaning, then you might want to consider getting a replacement.

9. While you are cleaning or replacing your impeller, we also recommend that you clean out pump housing, impeller cover, circular cover as well as other parts that look dirty as well.
10. Once you are done, put the impeller back into its original location and make sure that it is locked into the circular cover.
11. Next, put the impeller cover back on and then slide the pump back into the bottom of the filter.
12. Reattach the power cable to its channel and then slide the pump housing backon.
13. With everything reassembled, you should be able to safely plug your Seachem Tidal 75 or Seachem Tidal 110 hang-on-back filter back into the power outlet.
