What to Look for in a Canister Filter
A canister filter is a type of external filter. This simply means that the canister sits outside the tank, unlike internal filters and power filters that hang on the back of the tank. Aside from this detail, they work in much the same way as other filters to remove waste from the tank.
Here are some things to look for in a canister filter:
- High flow rate. The flow rate refers to how quickly the filter will turn over the entire tank volume – some go as high as 320 gallons per hour.
- Filter media. At minimum, you want a canister filter that supplies mechanical and chemical filtration, so make sure it can accommodate two types of filter media.
- Easy to set up. Most canister filters are fairly straightforward, but it doesn’t hurt to check the instructions before you buy to make sure it’s not too complicated.
- Simple to clean. Keeping your canister filter clean is essential for good water quality, so make sure the parts are easy to disassemble, clean, and put back together.
- Quiet to run. The downside of some external filters is that they can be noisy – look for a canister filter that doesn’t generate a lot of noise.
- Strong mechanical filtration. While chemical and biological filtration are important, you shouldn’t buy a canister filter that doesn’t do well in removing solid waste from the tank.
Remember, you don’t necessarily need to limit yourself to one filter. If you have a very large aquarium, it might be better to choose two medium-sized canister filters and install them at two sides of the tank so ensure proper filtration and water flow.
When it comes to choosing the best canister filter for your aquarium, there may not be a clear choice. The key is to consider your tank parameters – things like water volume, dimensions, and biological load – to determine what size filter you need. From there, you can take what you’ve learned here to narrow down the options and make an educated decision.
