What exactly are trickle filters?
Trickle filters are biological waste filtration systems. Many large aquarium owners use them to eliminate biological waste from their fish tanks. The filters are also gradually becoming popular with small aquarium owners. There are many types of trickle filters on the market. The best ones filter and eliminate biological waste excellently.
It is estimated that about 80 percent of the people who start aquariums quit before the end of two years. Why? Because aquarium maintenance (read: water changes) is a lot of hard work. However, what many of those who quit do not know is that by setting up a quality trickle filter, they can spend less time doing tank maintenance and more time enjoying spending time with their pet fish and doing other things.

How do they work?
Trickle filters for small tanks are located above the tanks. They contain a tower of filter media through which aquarium water is supposed to flow or trickle to be cleaned. For aquarium water to get to the top of the filter, it needs to be pumped. Therefore, if you want to set up a trickle filter, you need to buy it plus a submersible pump.
Once the water gets to the top of the filter, it flows downward by gravity through the filter media that traps biological waste. At the bottom of the filter, the cleaned water will trickle back into the fish tank.
If you set up a trickle filter, you will need to maintain it once in a while but it will largely reduce the amount of work you have to do to maintain your aquarium.
What are their benefits?
Trickle filters have many benefits. First, they are powerful biological waste filters. In other words, they will make sure your fish tank is devoid of biological waste. Second, they return highly oxygenated water. This is because all trickle filters have spray bars on top that spray the pumped water onto the media. This spraying aerates and oxygenates the water making it healthier for your fish when it gets back to the tank.
Third, they usually have aerial plants growing on the top filter because of the fish waste. These plants often improve their aesthetic quality and make them even more powerful filters. Fourth, they reduce the amount of tank maintenance that needs to be done. When you set up a decent trickle filter, you will no longer need to do so many water changes. This is because the water will be cleaner and also devoid of nitrates (which will be absorbed by the roots of the growing plants).
So as revealed by the statements above, trickle filters are very beneficial. If you can buy one right now you should do it. It will help you to improve the environment in your aquarium and cut down the amount of work you have to do to maintain it.
What not to expect from trickle filters?
There is no doubt that trickle filters are very efficient biological filters. They are more efficient biological waste filters than conventional filters and sponge filters.
However, you should note that they are neither chemical nor mechanical filters. So they do not provide any significant chemical or mechanical filtration.

This Eshopps wet dry filter is highly-rated by experienced aquarists and those who have used it. It is pricey but also one of the most complete trickle filters available online.
By complete, I do not mean it comes with a pump. You still have to buy a pump separately. By complete I mean it comes with filter material (bio-balls). The majority of trickle filters do not come with filter material or materials. You have to buy it or them separately.
When water is sprayed on top of the bio-balls (the filter material), it trickles down by gravity. As it trickles down, the biological waste gets trapped by the balls. This is how this filter does its work.
And with time the trapped biological waste will decay and this will lead to the formation of beneficial bacteria colonies on the bio balls. The bacteria will breakdown the nitrite and the ammonia in the water, which are harmful to fish.
