Things You'll Need
- Cup
- Large bowl
- Aquarium water
- Filter brush
Instructions
Scoop out three cups of water from your aquarium and pour it into a large bowl. Cleaning the sponge of your filter with water your fish is used to already can make the transition from a slightly dirty environment to a cleaner one a little easier.
Unplug your filter and remove it from the tank. Remove the sponge from your filter and clean it with the tank water, removing any build up. Put buildup aside on a paper towel to throw away, instead of in your bowl of water, as you'll want to use this water for future cleaning.
Dip a filter brush into your clean water and scrub the outside of your filter and inside the tubes. Dip your filter brush back into the water to rinse and continue cleaning the rest of your filter.
Replace water in your aquarium, then place the filter back in its spot and turn it on.
