Why Fish Tank Filters Are Important
The fish in your tank will produce ammonia, feces, excess food and other natural waste. If unfiltered, this waste can build up and have severe effects on your fish. Unbalanced water conditions may cause your fish to lose their appetite or coloration, reduce their energy and weaken their immune systems.
How to Choose the Right Filter
Select a filtration system that will work with the size of your tank, and the type of fish you want to keep. Of the many options available, it's also important to learn which types are recommended for fish that naturally produce more waste, and the maintenance it will require.
Types of Aquarium Filters
There are many kinds of aquarium filters available for you to choose from: under-gravel, canister filters, external and internal filters, and more.
- Power filters: These filters are known to be easy to maintain and designed to fit on the back of your aquarium.
- Under-gravel aquarium filters: These filters sit underneath your aquarium substrate, and are typically used with air stones to push water to the surface of the tank.
- Canister aquarium filters: These filters are placed beneath the aquarium, and it’s pressurized so that water can be forced through a fine filter to trap smaller waste matter.
