How to change the filter media in your Aqua One Nautilus 2700
Watch the guide or follow the steps.
- 1Turn the canister filter off at the power point and unplug it. Close the taps or flow valve and disconnect the tap connector from the head unit (Nautilus: lift the locking lever).
- 2Fill a bucket with water from your aquarium. Release the clips, lift off the head unit and take the media baskets out of the canister.
- 3Take out the sponges and the white wool. Dunk the baskets of biological media a few times in the bucket of aquarium water: Aqua One says this keeps the chlorine in tap water from killing the good bacteria on it.
- 4Rinse the sponges in the bucket of aquarium water and fit the new pads from the set where the old ones sat: Aqua One says to replace the wool regularly and the sponges once they clog.
- 5Put the media back in the same baskets and order, refit the baskets and head unit, then prime and restart the filter as its manual describes.
