Filtration for Tropical Fish Tanks
Filtration is the cleaning and moving of tank water, making it safe for fish to live in. The three main filtration systems in any aquarium include biological, chemical, and mechanical.
Biological filtration is when the beneficial bacteria break down ammonia and nitrite and convert them to compound nitrate. Chemical filtration is the removal of wastes from water by adding chemical additives. Finally, mechanical filtration is what most people envision when they think of filtration. It is the machinery that circulates and strains water through an aquarium filter to remove solid particles. This can sometimes cause bubbles in your fish tank, but it is natural.

How Much Filtration for a Tropical Fish Tank?
The water in a tropical fish tank should go through the filter at least 3 to 4 times per hour to effectively maintain it. When choosing a filtration system to purchase, consider the type of filtration it has. Some systems will combine the various types of filtration, so it is important to check before purchasing.
Let us now discuss what internal filters are. Internal filters, also identified as a box or corner filter, were the first to be produced for use in aquariums at home. An internal filter is placed in the back corner of a fish tank, with the outlet below the water’s surface. Water is sucked into the filter’s bottom and pulled through a rough sponge that soaks up debris.
Bacteria grows in the polluted and oxygen-rich water that passes through the sponge, and they convert toxic substances such as ammonia to nitrite and nitrite to nitrate. Most internal filters are inexpensive and are widely available in pet stores and online.
Conclusion
There are numerous internal filters on the market; some may be more expensive, but you can definitely find some at a low cost. Filters are essential in a fish tank because the water can become polluted without them. This may cause your tropical fishes to become sick, or even die. When it comes to selecting a filter for your fish tank, look for one that has three stages of filtration (chemical, biological, and mechanical), is long-lasting, and is of high quality.
