What does the undergravel filter do?

Aquarium gravel is on the undergravel filter board. It draws water from below the plate, which in turn draws water from the gravel. The nitrifying bacteria that live there use dissolved oxygen to metabolize ammonia and nitrite as the water passes into gravel grains. These fish tank filters provide an effective way to reduce ammonia and nitrate concentrations in the aquarium water and are easy to install and inexpensive.

Is the undergravel filter system efficient?

A filter under gravel is comparatively cheap, reliable, and very effective. Biological aquarium filters including under gravel filters are fully functional and have a completely different design. The undergravel filter acts as a mechanical filter, as well as a biological filter because it collects solids on the gravel bed.

How is the sub gravel filter cleaned?

The cleaning of such filters is challenging because they have sunk underneath your tank substratum but for basic maintenance, at least you should vacuum the gravel every two weeks. When cleaning this filter type, coordinate it with your regular change in water because it is the best cleaning method to vacuum the gravel over the filter. Undergravel vacuums are drawn through the gravel by suction tank water and then returned to the tank via air stone. The filter bed must be released. The gravel gets compacted over time and solid debris accumulates within the substratum.

Why do I use the filter undergravel?

The purpose of the subgrave filter in your aquarium provides the two basic elements in your fish tanks: the good filter media basis for strong biological filter growth and clean, clear water.

Conclusion

Undergravel filters remain popular because they work well, easy to use, and are relatively economical, even though they are not the only biological filtering method available.

Alternative methods like a canister or trickle filter are equally effective, yet much more expensive. Sponge filters have much smaller nitrification capacity than most under-gravel filters. While biological filtration is essential for the well-being of most aquariums, it is equally true that the precise place in the system of such filtration is irrelevant.

Whatever the required nitrification is completed, the primary issue is that any needed maintenance is done regularly and faithfully. This improves the aquarium’s long-term success and its owner’s fulfillment.
