What are the filter systems of the fish tank? This is a question that many friends have been asking recently. The editor still knows a little about it. Let's take a look!

What are the filter systems for fish tanks?

1. Upper filter system: The upper filter is placed in the upper part of the aquarium. It pumps the water in the fish tank upwards into the upper filter tank through the submersible pump, and then the water flow stops. It will flow back into the tank from the water outlet at the lower part of the filter tank through the biochemical filter material such as filter cotton and biochemical cotton.

2. Drip filtration: This is a filtration system with perfect physical and biochemical filtration and good filtration effect.
