We are glad to do all this work for you so that you get to know just as much as we do about the best freshwater aquarium filtration system without spending countless hours surfing the web.
Flow rate is important
One of the main things you want to check is the flow rate of the filter, which is measured in gallons of water per hour or GPH. While the best aquarium filter can pump up to 500 GPH, that doesn’t need you necessarily need it.
You also need to take the size of your tank into account. If you have a large tank of around 90-100 gallons, then this powerful filter is just fine. But for a 20-gallon aquarium, the flow rate is way too high, filtering 25 times the tank’s entire capacity in just one hour.
Depending on the fish species you have, you might also need to take flow rate into account. Some species release a lot of residual matter in the water and that requires constant filtering at high flow rates. Other fish prefer a quieter environment which means lower flow rates. The good thing is that most filter systems come with an adjustable flow rate mechanism, just remember that most of them allow for a maximum of 50 percent reduction in flow rate.
A bit about filters
Some filters come with single filter cartridges, others have 3-stage systems which use layered filters such as activated carbon, bio foam filters, sponges, etc. For small aquariums or low maintenance fish, simple filters can do a more than decent job. However, you may want your fish to benefit from a clean and healthy environment to live in, and the more filters there are, the better the water quality.
Replaceable filters are good for keeping beneficial bacteria
Some filters are easy to replace while others require removing the entire filter system. There are also models where you can replace filters one at a time, allowing the beneficial bacteria which handle the breakdown of nitrates and ammonia to stick to the remaining filters so that you don’t have to wait for a few weeks for the colonies to replenish.
